Yes it's been answered and thanks to everyone who took the time to respond.

My hpi check isn't the important part here, even if I hadn't done one when I bought the car, the above statements about the trader doing the checks still stands. It simply adds further weight around me being unaware that the car was clocked.

Yup! It would be different if I'd sold to a private buyer. But as a trader he has further responsibilities when buying a car.

I an update for you all. I've had an interesting day. I've spoken to CAB and adviceguide.org and they both quoted from the documentation they had which was: If you buy a car from a private seller you won't have the same rights as when you buy from a dealer. You will only be able to take action against the seller if 'the vehicle doesn't match the description they gave you, for example, they told you it had only one owner when it had several. The seller will be responsible for giving a false description, even if they believed it to be true. So I presumed this meant mileage etc which would mean the the trader had the ability to claim back from me. But I've just had a conversation with a solicitor and she said that, the motto is buyer beware. He is a dealer, he could have made proper inspections or enquiries at the time and indeed you would expect that to happen. He did not. If you did not know about these matters and had no reason to suspect, you can not be liable in any way. Therefore I can reject the request to refund partially or whole. I can prove I had the HPI check done at the time of purchase and saw MOT certificates and service history, which in her opinion, is enough to prove I had no reason to suspect anything was untoward when I bought the car. He's a dealer and It's his job to know about acts etc. Therefore I can reject the request to refund partially or whole.

I'm not a trader, I'm a private individual who sold the car via an advert on eBay and a trader bought it

The HonestJohn link isn't me. It's a similar situation to mine. I bought the car privately off an advert on gumtree, didn't get a receipt but should be able to find the old advert. I sold the car privately via an advert I put on eBay.

Sorry Sam, just always a bit nervous about putting too much Info on an open forum. Thanks Dacouc for the link. He did start telling me I could be prosecuted for fraudulent documents etc so I spoke briefly to the police. They told me it was a civil matter and not something that would go through them.

Thanks guys, appreciate the advice, going to talk to a solicitor tomorrow too. It was an old people carrier for £3500

The mot with the lower mileage was registered with DVLA before I owned the vehicle so, IMO (which isn't much hence asking here) proved that I couldn't have clocked the mileage on the car as it was already done when I bought it. I have been naive and didn't check myself on the website (but didn't realise I could do this). But the hpi was clear and service book etc tallied up - although I do realise now this isn't always proof. I think the guy is an I dependant trader who buys and sells card from his house rather than someone with a forecourt (that's how it appears anyway)

Hi thanks for the response. I'll try and answer all your questions below. The mileage discrepancy is large. I sold the car in October I believe he is taking the car back and refunding his customer He hasn't said how much he wants, but by my reckoning the difference in how much I sold him the car, and his much it would be worth had we known the proper mileage would be about £2000. I also bought the car privately but no longer have the details. Just for info, I'm not a trader but a private seller

Sorry, also worth mentioning that I bought the car with the mileage I sold it with (plus any mileage I did) I've since looked on the DVLA website and you can see the last MOT (last year), well before I bought it had the lower mileage showing, and then before then, the higher mileage, so you can see the alterations in the mileage were done before I owned the car.

Hi, I'd like some advice please? I bought a car privately some time ago, ran it for about 6 months and then sold it via eBay as my personal circumstances changed. I sold it to a trader. I had a phonecall the other day as it looks like the car has been clocked. I did a hpi check when I bought it and it all came back clear. It had 10 months mot on it when I bought it, plus various service history and receipts. It sounds like the trader has sold it on and his buyer has found out it's been clocked. The trader now wants some money back off me or he's going down the legal route. Can he do this?
