# Questions to Ask When Buying a Used Car

Published 27 September 2026. CarCheckUp guide: https://carcheckup.co.uk/blog/questions-to-ask-when-buying-a-used-car/

> The right questions tell you a lot about a used car and its seller. Here are the questions to ask before viewing and during the viewing, and the answers to watch for.

Asking the right questions before and during a viewing can save you a wasted trip, or a bad buy. Ask them in a friendly way; honest sellers are happy to answer.

## Before you go to see the car

- **“Is the car registered in your name at this address?”** The seller should be the registered keeper on the V5C, and you should view the car at the address on it.
- **“What is the registration?”** A genuine seller will give it. Run a [free check](https://carcheckup.co.uk/) before you travel: it shows the MOT history, recorded mileage and whether the details match the advert.
- **“Why are you selling it?”** A clear reason is reassuring; a vague one is worth a follow-up.
- **“Is there any finance on the car?”** Even if they say no, check for [outstanding finance](https://carcheckup.co.uk/outstanding-finance-check) yourself.

## About the car's history

- **“How long have you owned it?”** A very short ownership may mean a problem the seller discovered. Compare it with the [number of previous keepers](https://carcheckup.co.uk/dvla-previous-owners), and see [how many owners is too many](https://carcheckup.co.uk/blog/how-many-previous-owners-is-too-many-for-a-used-car/).
- **“Has it ever been in an accident or written off?”** Check the answer against the [write-off record](https://carcheckup.co.uk/written-off-vehicle-check).
- **“Does it have a service history?”** Ask to see the book and invoices, and check the mileage goes up steadily.
- **“When was the cambelt changed?”** (If the engine has one.) It's an expensive job that's often due on older cars.
- **“Are there any known faults?”** In a private sale, the seller's description matters legally, so note what they say.

## During the viewing

- **“Can I see the V5C?”** Check the name, address and VIN, and that the V5C looks genuine.
- **“How many keys are there?”** Replacement keys can be expensive, and a missing key can be a theft warning sign.
- **“Has the recall work been done?”** See [how to check for recalls](https://carcheckup.co.uk/blog/how-to-check-if-a-car-has-an-outstanding-safety-recall/).
- **“Can I take it for a test drive?”** Use our [test drive checklist](https://carcheckup.co.uk/blog/used-car-test-drive-checklist-what-to-check-and-listen-for/).

## Answers that should make you walk away

- “The V5C is in the post” or “I'm selling it for a friend.”
- Refusing to give the registration or let you check the car.
- Pressure to pay a deposit before you've seen it, or to pay in cash only.
- Answers that don't match the car's records.

## Key points

- Get the registration before you travel and check it.
- Ask about ownership, finance, accidents, service history and keys.
- Know your rights: [dealer vs private seller](https://carcheckup.co.uk/blog/buying-from-a-dealer-or-a-private-seller-your-rights/).
