How to Buy a Used Car: 22 Steps

The price on the windscreen is not the budget. A €10,000 car typically costs €12,000–€12,500 in the first year once insurance, road tax, an immediate service, tyres and a repair reserve are added. If that second number is not available, the first number is too high.

Build the budget in four lines: purchase price, first-year running costs (insurance quote before you buy, annual tax, one service, a set of tyres), immediate fixes (the things you already know about), and a repair reserve of roughly 10% of the price. The reserve is not pessimism; it is the line that stops a €400 fault becoming a credit-card decision.

Decide how you will pay before you view anything. Cash, bank transfer or dealer finance each change your negotiating position, and a private seller may not accept anything but cleared funds. If you need finance, get the rate and the total cost approved first, not at the desk after you have fallen for the car.

Before browsing, write five requirements in priority order. Typical ones: five seats and a usable boot, automatic gearbox, petrol rather than diesel for short trips, under 4.3 m for city parking, and a low emission sticker for a low-emission zone. Be specific enough that a listing can pass or fail.

Then mark the top two as deal-breakers and the bottom two as negotiable. This is the list you will use in step 6 to reject cars in ninety seconds, and in step 17 to walk away from a car you like but cannot live with. Without it, every viewing becomes a fresh argument with yourself.

Add one negative requirement too: the thing you will not accept. A sunroof that leaks, a panoramic roof, a dual-clutch gearbox out of warranty, a colour you hate, a modified car. Naming it now is cheaper than discovering it in the rain at a viewing.

Choose three models, not thirty. Two body styles at most. For each, pick a two-year window — usually the third to fifth year of production, after the first facelift, when the depreciation curve has flattened but the car still has most of its life left. A three-to-six-year-old car with 60,000–90,000 km is the normal sweet spot.

Research each model's known faults before you look at one: timing chain or belt interval, dual-clutch or CVT behaviour, diesel particulate filter problems on short trips, infotainment failures, and recall history. Owner forums and independent motoring magazines are more useful here than the seller's enthusiasm.

Check crash-safety ratings for the generation you are considering, not the current one — a model that scored well in 2019 may have been tested under different rules. Euro NCAP publishes results by year and variant, which is exactly the granularity you need when comparing two similar cars.

Two cars at the same price can differ by €1,000 a year in running costs. Compare four things per model: insurance group (get a real quote on the exact trim), annual road tax or CO2-based charge, tyre size and price, and service interval plus the big-ticket item — timing belt, clutch, dual-clutch oil, or battery health on an electric car.

Diesel deserves a separate line. A modern diesel with a particulate filter is a poor choice for a car that does mostly 5 km school runs; the filter clogs, the car enters regeneration cycles, and the repair is expensive. Petrol or a hybrid usually suits that pattern better, even at slightly higher fuel consumption.

Electric cars shift the comparison: no oil changes and lower service costs, but insurance can be higher, tyres wear faster because of weight, and battery condition is the single most important check. Ask for a state-of-health report, not just a range estimate from yesterday's drive.

Search three channels in parallel: franchise approved-used (warranty, higher price), independent dealers (mid-price, variable quality), and private sellers (lowest price, least protection). Set saved alerts for your three models with the mileage and year limits from step 3, and widen the radius to about 90 minutes of travel — the right car is often one town away.

Use the same filters on every channel and compare like with like: same generation, similar mileage, similar trim. Three comparable listings give you a market price; one listing gives you an asking price. Save the three adverts as screenshots with the date, because listings disappear when a car sells and you will want the evidence in step 17.

Do not buy from a listing you have not seen in person, and do not send a deposit to hold a car you have not inspected. Distance selling rules can protect an online purchase from a trader, but they do not replace an inspection, and they rarely help with a private sale.

A listing is a set of claims, and the gaps are as informative as the text. Read it in this order: number and angle of photographs (missing engine bay, missing rear quarter, missing interior usually means something), background (the same street for every photo suggests a trader posing as a private seller), mileage pattern against the year, and service mentions with dates and stamps.

Flag these phrases for extra questions: “sold as seen”, “no timewasters”, “recently serviced” without a date or invoice, “small dent” without a photograph, “first to see will buy”, and any advert that lists a long list of recent repairs — sometimes honest, sometimes the end of a problem chain.

Check the test history if the country publishes it. In the UK, the MOT history is free and shows every advisory and failure by date and mileage; a car that failed on the same item three years running is a car with a known weakness, not a bargain.

Send the same five questions to every seller, in writing, before you agree to a viewing. Why are you selling? How long have you owned it, and how many keepers before you? Do you have the full service history and the registration document in your name? Are there any faults, warning lights or accident repairs? Can I see the car cold, and can my mechanic inspect it?

The answers matter less than the pattern. A seller who answers all five with dates and details is easier to deal with than one who replies “it's all good, just come and see”. A refusal on the cold start or the inspection is not a negotiating position; it is the answer.

Also ask for the VIN before you travel, and check that it matches the photographs and the advert. It costs the seller nothing and saves you a wasted Saturday. If the seller will not send it, move to the next car — there are three on your list for exactly this reason.

A vehicle history check is the cheapest insurance in the whole process, usually €10–€25. Give the VIN to a recognised service and read five sections: outstanding finance, write-off or salvage markers, stolen record, mileage inconsistencies, and import or previous-country history. A car with finance still attached can be repossessed from you, even if you paid in good faith.

Cross-check the mileage yourself. Every test record, service invoice and advert should agree, and the mileage should rise in a straight line. A car that was 120,000 km at its last test and 70,000 km today has a story that no seller can talk away. Clocking is less common than it was, but it still exists on older cars and imports.

Check for open recalls too. The EU Safety Gate database lists vehicle recalls by make and model, and a dealer can confirm whether the recall work was done. An outstanding safety recall is the manufacturer's job, not yours, but you want it scheduled before you buy.

Before a test drive, check four things. The registration document — V5C in the UK, carte grise in France, Fahrzeugschein in Germany — is in the seller's name and matches the VIN on the car. The service book has stamped or invoiced services with dates and mileage. The test certificate is current and the advisories are readable. And there are two keys, both working, with the remote functions tested.

Look at the VIN in three places: the windscreen or door jamb plate, the stamped chassis number, and the paperwork. They should be identical. On imported cars, check that the registration matches the country you are buying in and that duty and VAT were paid; an import with unclear paperwork is a problem you inherit.

Count the keys and check the locking wheel-nut key. A missing second key is €150–€300 to replace and a sign the car was cared for casually. A missing locking nut key is a tyre-change problem on day one. Both are legitimate price points in step 17.

View in daylight, in dry weather if you can choose, at the address where the car is kept. A car that lives on a street with trees will have different paint and trim wear from one kept in a garage, and you want to see the environment, not a supermarket car park arranged for the meeting.

Bring a torch, a small magnet, an old towel to kneel on, and your printed checklist. Bring a second person if possible: one talks to the seller while the other looks at the car, and the second person is the one who says “we should leave” when you are busy being polite.

Tell someone where you are going and photograph the car's location and plate on arrival. If the seller insists on meeting somewhere neutral, that is acceptable, but it is also a reason to be more careful about the paperwork and the payment in step 19. Never view a car at night, in rain, or alone in an isolated place.

Ask the seller not to start the car before you arrive, and check that the bonnet is cold to the touch. A warm engine starts easily, idles smoothly and hides a tired battery, a failing glow-plug circuit or a chain rattle that disappears after thirty seconds. The cold start is the single most informative minute of the whole viewing.

Listen for: a long crank, a metallic rattle on start-up (timing chain), a puff of blue smoke (oil), white smoke that persists (coolant or injectors), black smoke under revs (diesel mixture), and any warning light that stays on after the dashboard self-test. Rev gently once warm and listen for exhaust blows and turbo whistle.

Then check the simple things while the engine idles: air conditioning blows cold within a minute, the heater works, the glow-plug light behaves on a diesel, and there are no messages on the dashboard. A seller who will not let you do this has told you something useful without saying a word.

Start at the front and walk the car once, slowly, with the torch at a low angle. Look for panel gaps that are uneven from one side to the other, paint that changes tone between adjacent panels, overspray on glass and rubber, and rust at wheel arches, sills, the boot floor and the base of the windscreen. A magnet slides over steel and sticks to filler only weakly; run it along the sills and rear quarters.

Check the glass: chips in the windscreen, mismatched date codes, scratches from a worn wiper. Check every tyre: matching brands and sizes, date codes within six years, even wear across the tread, and no cracking on the sidewalls. Four matching quality tyres are a €400–€600 item, and mismatched cheap tyres tell you how the car was maintained.

Look underneath with the torch: fresh underseal can hide rust, and a clean, dry floor is what you want. Check the exhaust for holes, the suspension for leaking shocks, and the brake discs for deep scoring. Note every defect with a photograph; step 17 needs the list.

Sit in the driver's seat and set it to your driving position before judging anything else. Then work through the controls in a fixed order so you do not miss one: windows, mirrors, seats, seatbelts, lights, indicators, wipers, horn, air conditioning, heater, radio, reversing camera and parking sensors.

Look for wear that does not match the mileage: a worn driver's bolster at 60,000 km is normal, a worn pedal rubber and a shiny gear knob at 40,000 km is less so. Check the boot for water under the spare wheel, damp carpets, and a smell of smoke, pets or perfume — perfume is sometimes used to cover damp.

On a modern car, check every screen for warning messages, service-due reminders and software faults, and confirm that both keys are recognised. On an electric or hybrid, ask to see the charge state and the battery health screen, and note whether the car has a heat pump if you live somewhere cold. A control that does not work is a repair, not a quirk.

Ask for a twenty-minute drive on roads you choose: five minutes in town, ten on a back road with some bends, five at highway speed. The seller comes along, and you drive — this is a test, not a chauffeur service. Check that the car is insured for a test drive before you move it.

In town, test the clutch bite point, the gearbox from first to third, the brakes at low speed and the steering on a full lock. On the back road, listen for suspension knocks over bumps, feel for pulling under braking, and check that the car tracks straight on a flat road. At speed, look for vibration through the wheel, wind noise, and a temperature gauge that stays where it should.

After the drive, park, leave the engine running and look under the car for fresh drips. Check the tyre pressures when cold if you can, and look at the brake discs again now that they are warm. A twenty-minute drive finds more than an hour of idling ever will.

Book a pre-purchase inspection with an independent garage, not the seller's workshop and not a service that inspects only the paint. A good inspection takes 60–90 minutes on a lift and covers fault codes, brakes, suspension, tyres, leaks, corrosion, exhaust and, where relevant, battery health. Expect €80–€150; a specialist marque inspection can be more.

Give the inspector your own defect list and ask for a written report with photographs and a repair estimate for anything that fails. Ask specifically about the items your model is known for from step 3 — timing chain, dual-clutch, particulate filter, battery degradation — because a generic check will not look for them.

If the seller refuses an inspection, walk. There is no legitimate reason to refuse a mechanic you are paying for, and the refusal is worth more than any explanation. If the inspection finds structural rust, a bent chassis or a major engine fault, the car is finished regardless of the price.

Service history is a timeline, and the useful question is what is missing. Check the interval the manufacturer specifies, then look for every service at the right mileage or the right year, whichever comes first. A car with 100,000 km and four services is not “full history”; a car with 100,000 km and eight dated invoices is.

Look for the big-ticket items specifically: timing belt or chain, water pump, brake fluid, gearbox oil on an automatic or dual-clutch, coolant, spark plugs, and the diesel particulate filter if it applies. These are the jobs that separate a maintained car from a car that merely passed its test. A recent cambelt invoice is worth more than a recent oil change.

Read the test advisories as well as the pass. Advisories repeat for a reason: corroded brake pipes, worn suspension, tyre wear, oil leaks. Three years of the same advisory is a repair you will inherit. If the seller has no paperwork at all, price the car as one with no history — because that is what it is.

Set your walk-away number before you sit down: the price at which you are still happy after the inspection, the reserve and the first service. Then open with evidence, not an insult. “The inspection found worn front discs, two tyres at the limit and a leaking shock; my quotes are €700. I am comfortable at €X.” That is a negotiation, and it is hard to argue with a written report.

Use the three comparable adverts from step 5 as the market frame. A dealer has less room on price but more room on warranty, a fresh service, a second key or tyres. A private seller has more room on price and none on warranty. Ask for the thing that costs them least and you most: a new test, a service, four tyres, or the second key.

Never negotiate with a deposit you cannot get back. If you leave a deposit, write the amount, the refund conditions and the collection date on the receipt, and pay by a method with a record. “I will hold it for you” is not a contract; a signed line is.

A used-car agreement does not need a lawyer; it needs the facts. Write the VIN, registration, mileage at sale, price, deposit and refund terms, any faults disclosed, what is included (keys, mats, winter tyres, warranty), and the collection date and place. Both parties sign and date it, and each keeps a copy or a photograph.

Know which protection you have. A dealer in the EU must sell a car that conforms to the contract, and consumer law gives you a minimum period to raise defects — at least one year in most member states, two in some. A private sale is usually “as described”, with far less recourse, which is why steps 11–16 matter more, not less, when buying privately.

Keep the advert, the messages, the inspection report and the receipt together. If a fault appears in the first weeks, that file is the difference between a repair and an argument. Do not accept a verbal promise about a warranty; ask for the policy document and read what it excludes.

Pay at collection, with the car, the keys and the signed documents in front of you. A bank transfer is the normal method: it is traceable, and the seller can confirm receipt before handing over the keys. Avoid cash for large sums, and avoid anything irreversible — gift cards, crypto, payment to a third party, or a “holding deposit” to someone you have not met.

Check that the account name matches the name on the registration document. If the seller says the car belongs to a relative and asks you to pay someone else, stop; that is a classic fraud pattern and a legitimate seller can sort the paperwork before you pay. For a dealer, pay the business account and get a proper invoice with the VAT treatment shown.

Get a signed receipt on the day: date, amount, car, VIN, mileage, and the words “sold with keys and documents”. Photograph the odometer, the keys and the signed receipt together. Then take the car home insured — step 21 is the same afternoon, not next week.

Complete the ownership transfer as soon as the sale is done, and in the same week at the latest. The exact process depends on the country: in the UK the seller completes the V5C and you receive the new document; in Germany, France, Spain and Italy the registration and plates follow a local procedure, sometimes with the plates changed. Ask the seller to do their half on the spot, and photograph both halves before you part.

Keep every document you are given, including the export or transfer certificate, the invoice, the test certificate and the service file. Register the car to your address, add it to any toll, parking or low-emission-zone account, and check whether the plates or the registration trigger a tax transaction in your country.

If you bought across a border, confirm the import rules before you travel home: export plates, temporary insurance, VAT and duty, and the registration inspection in the destination country. A cheap car in another member state can become an expensive paperwork project if you skip this step.

Arrange insurance before you collect the car, not after. You need at least third-party cover to drive legally in every European country, and comprehensive cover is worth pricing on the exact model, trim and registration before you commit — a quote on “a 1.4 petrol” can double on the actual car once the insurer sees the VIN.

Tax the car the same day if your country requires it. In the UK, vehicle tax is checked electronically and cannot be transferred from the seller; in many other countries the tax is annual and handled at registration. Ask the seller to show the car is currently taxed, and be ready to pay from the first day of your ownership.

Add breakdown cover if the car is older or you drive long distances, and tell the insurer about any modification, tow bar or private plate. A modification you did not declare can void a claim. Keep a copy of the certificate in the car and a photograph of it on your phone.

In the first week, check the fluids cold: oil, coolant, brake fluid, screen wash, and the tyre pressures including the spare if there is one. Look under the car after two nights for drips, and note any new noise or warning light in a small notebook with the date and mileage. This is your baseline, and it is the evidence you will need if a fault turns out to be covered by a dealer warranty.

Book a service at the interval the manufacturer specifies, even if the seller said it was recently done; the invoice and the date are worth more than the claim. Change the cabin filter, check the wiper blades, and clean the interior — a car you maintain from week one is a car you will notice problems in.

Then set the maintenance fund from step 1 at €50–€100 a month. A used car costs money whether or not it breaks; the fund turns a €600 clutch from an emergency into a line item.
