Questions to Ask When Buying a Used Car: The UK Checklist

A used car can be a brilliant buy or a costly headache, and very often the only thing standing between the two is the questions you ask before any money changes hands. A confident seller will happily answer them. A dodgy one will dodge, waffle or rush you. Either way, the questions below tell you what you are really dealing with. Run through them in order, listen as much to how they are answered as to what is said, and you will spot most problems long before they become your problem.

Start with the car's history

The story of the car matters as much as how it looks on the day. These questions get at where it has been and what it has been through.

• How many owners has it had? Lots of owners in a short space of time can hint at a car people were keen to get rid of.
• Do you have the full service history? A complete, stamped service book or digital record is gold. Patchy or missing history is a bargaining point at best and a warning at worst.
• Has it ever been in an accident or written off? Ask directly. A car that has been a write-off and repaired can still be legal to sell, but you deserve to know before you buy.
• Why are you selling it? An honest answer is usually mundane: a growing family, a new job, an upgrade. A vague or shifting story is worth a second thought.
• Is there any outstanding finance on it? This is a big one. If money is still owed on the car, it does not legally belong to the seller to sell, and you could lose it. Never skip this question.

Then dig into condition and how it drives

Now get specific about the mechanical side. You are looking for honesty and detail, not a sales pitch.

• When was the last MOT, and what came up on it? Advisories tell you what is wearing out next. You can cross-check the answer against the free government MOT history record.
• Has the timing belt been changed, and when? On many cars this is an expensive scheduled job. If it is due and undone, factor that into your offer.
• Are there any warning lights or known faults? Ask plainly, then check the dashboard yourself when you start it.
• Can I see it started from cold? A seller who warms the engine up before you arrive may be hiding a tricky cold start. Ask to see it fired up cold.
• Can I take it for a proper test drive? A reluctant seller here is a red flag. You want a decent run that includes a mix of speeds, not a lap of the car park.

Check the paperwork lines up

Documents are where a story either holds together or falls apart. Take your time over these.

• Can I see the V5C logbook? Make sure the seller's name and address match, and that the details match the car in front of you.
• Does the mileage match the records? Compare the odometer with the service history and MOT records. A mileage that jumps around is a classic sign of clocking.
• How many keys come with it? A replacement key can cost a surprising amount, so two is reassuring and one is a small negotiating point.
• Is it still under any warranty? Some newer used cars still have manufacturer warranty left, which is worth having confirmed in writing.

Talk money and the deal

Once you are happy with the car, the conversation turns to price. Politeness and a few well-aimed questions do most of the work here.

• Is the price negotiable, and what is your best price? Most used prices have a little give in them, especially if your history and condition checks turned up anything.
• What is included in the price? Mats, a service before sale, a fresh MOT, a spare key. It is worth knowing what you are actually getting.
• If buying on finance, what would the monthly payments be? Always look at the total cost and the interest rate, not just the headline monthly figure.

If you are likely to spread the cost, it helps to work out the real monthly figure before you sit down to haggle. You can do that with the calculator below. It is also wise to budget beyond the purchase price, since insurance, tax and upkeep all add up, which our guide to average car running costs in the UK sets out.

Buying from a dealer or a private seller?

Who you are buying from changes both your questions and your protection. From a dealer, ask what warranty or guarantee comes with the car, whether it has been through any pre-sale checks, and what their returns policy is, since buying from a trader gives you more consumer rights if something is wrong. From a private seller, you have fewer legal protections, so lean harder on the history and paperwork questions, and be extra wary of anyone who will not let you view the car at their home address or see the logbook. Whoever you buy from, run the registration through the free government records to confirm the basics. You can check a car's MOT history on GOV.UK.

Answers that should make you walk away

Some replies are louder than the words in them. Be ready to walk if a seller refuses a test drive or an independent inspection, cannot or will not show the V5C, gives a mileage that does not match the records, is cagey about outstanding finance, or pressures you to decide on the spot or pay a deposit before you have seen the car. None of these on its own proves anything sinister, but any of them is a reason to slow right down. A good car from an honest seller will still be there once you have done your checks.

Buy with your eyes open and the right questions ready, and a used car is one of the smartest purchases you can make. Rush it, skip the awkward questions, and it is one of the easiest ways to lose money. The list above costs nothing to use and can save you thousands.
