Buying a used car from a private seller can be a fantastic way to get more car for your money, cutting out the dealer's markup. However, it also means you're operating without the safety net of consumer rights that you'd get from a registered trader. The onus is on you, the buyer, to uncover any hidden problems. The good news is that a simple ten-minute phone call, armed with the right questions, can save you from a wasted journey and a potential money pit. This is your script to vet the car, and the seller, before you even think about seeing it in the metal.
1. Why are you selling the car?
This is a great opening question to gauge the seller's honesty and motivation. You are listening for a plausible, straightforward reason.
- Good answers: "I have a new company car," "We need a bigger (or smaller) car for the family," "I'm moving abroad," or "It's no longer ULEZ compliant for my commute." These are logical reasons to sell a perfectly good vehicle.
- Red flags: Vague, evasive answers like "just fancy a change" or "personal reasons" can be a sign of someone trying to offload a problem. If they've only owned the car for a few months and are already selling for a "change," be extra cautious.
2. Is the car registered in your name, at your address?
This is a non-negotiable security question. The person selling the car must be the registered keeper named on the V5C (logbook).
- Good answer: A simple, confident "Yes."
- Red flags: Any answer other than "yes" is a major problem. Excuses like "I'm selling it for my brother/aunt/mate," "I never got around to sending off the paperwork," or "The new V5C is in the post" are all signs you could be dealing with a 'curbsider' – a dodgy trader posing as a private seller. If the seller and the registered keeper details on the V5C don't match, walk away.
3. How long have you owned it?
This question helps to build a picture of the car's recent life. While short ownership isn't automatically a problem, it can sometimes indicate an issue the seller quickly discovered and now wants to pass on.
Check the number of previous keepers on the advert or ask the seller. A high number of keepers in a short period can suggest the car has been problematic and passed around. A RegRadar check will confirm the date of the last keeper change, allowing you to verify the seller's claim.
4. What's the service history like?
A car's service history is its CV. You want to see evidence of regular, timely maintenance.
| History Type | What it Means | Verdict |
|---|---|---|
| Full Main Dealer | Serviced on schedule by the manufacturer's own garage. The gold standard. | Excellent |
| Full Specialist | Serviced on schedule by a garage specialising in that brand. | Very Good |
| Part History | Some stamps/receipts, but with gaps in the record. | Be Cautious |
| Self-Serviced | Owner claims to have done the work themselves. No official stamps. | High Risk |
Ask if they have the stamped service book and a folder of receipts for work carried out. Receipts are often more valuable than stamps, as they detail exactly what work was done. A seller who has kept a meticulous file of paperwork is likely to have been a caring owner.
5. Can you tell me about the MOT history?
While the current MOT certificate is important, the vehicle's entire MOT history is a treasure trove of information, and it's all publicly available on the GOV.UK website. Ask the seller about it first to see if they are upfront.
- Good answers: "It's always passed first time," or "It failed once on a tyre and a bulb, but it was fixed straight away."
- Red flags: A long list of failures and advisories for the same items year after year (e.g., "corrosion on brake pipes" or "play in suspension joint") can point to an owner who only does the bare minimum to get a pass, rather than properly maintaining the vehicle. A vehicle check can compile this MOT history for you, making it easy to spot recurring patterns.
6. Has the car ever been in an accident or written off?
You must ask this directly. A seller should declare if a car is a "write-off" (also known as a Category S or N).
- Category N: Non-structural damage. Can be perfectly fine if repaired professionally.
- Category S: Structurally damaged, but deemed repairable. Needs to be inspected with extreme prejudice.
If the seller admits to an accident, ask for the paperwork from the repair. If they are hesitant or deny any knowledge, be wary. A premium vehicle history check is the only way to be certain, as it checks the MIAFTR (Motor Insurance Anti-Fraud and Theft Register) database for any write-off records the seller might "forget" to mention.
7. Is there any outstanding finance on the car?
This is a critical question. If you buy a car with outstanding finance, the finance company still legally owns it and can repossess it from you, even if you've paid the seller in full.
- Good answer: "No, it's owned outright."
- Red flags: "Yes, but I'll pay it off with the money from the sale." This is a huge risk. The seller could take your money and not settle the finance, leaving you with no car and no cash. The only safe way to proceed is to pay the finance company directly with the seller present. The easiest way to verify this is with a proper vehicle check from a provider like RegRadar, which includes a comprehensive finance check.
8. When was the cambelt or timing chain last changed?
For cars with a timing belt (cambelt), this is one of the most important and expensive maintenance jobs. They have a recommended replacement interval, either by mileage or age. A snapped belt will cause catastrophic engine damage.
Ask the seller if it has been done and if they have the invoice to prove it. If the car has a timing chain, ask if there are any rattles on a cold start, which can signify wear. Forgets to mention this? That's a potential four-figure repair bill waiting for you.
9. How many keys do you have?
Modern car keys are complex and expensive to replace, often costing hundreds of pounds. Asking this simple question can save you a nasty surprise. Ideally, the car should come with two working keys. If there's only one, you'll need to factor the cost of a replacement into your offer and consider the security implication of a lost key being out there somewhere.
10. Do you have the V5C logbook with you?
This is the final check before you agree to travel. This is different from question #2. You've already established it's in their name; now you need to know if they physically have it.
- Good answer: "Yes, it's here ready for you to inspect when you view the car."
- Red flags: "I've lost it and applied to the DVLA for a new one." Do not buy a car without the current V5C present. You cannot tax the car without it, and it's a huge fraud risk. A missing logbook is the number one excuse used by car thieves and scammers. Thank them for their time and hang up.
Bottom line
This simple phone call script is your first line of defence. It helps you filter out dishonest sellers, stolen vehicles, and rolling money pits without ever leaving your home. A seller who can confidently and honestly answer these ten questions is likely selling a genuine, well-kept car. If you get good answers, your next step is to arrange a viewing and, of course, run a full RegRadar vehicle history check to verify everything they've told you.
