I've bought a used 2010 Skoda Octavia VRS.

When purchased, I purchased on the assumption that at 21,000 miles the car was on its original engine. I later found out that only one month before purchase the engine was replaced by Skoda under warranty as an "Exchange" engine. I think its a new engine, but Skoda did not use these words when I asked them.

I've phoned the dealer who says it can actually be seen as a better car with a new engine than one which has done the full 21,000 miles. I am worried about the impact a cars service history which shows an engine change at less than 21,000 miles will have on any future part-exchange value?

Does the fact the car has had a new engine affect its value at all? Should the dealer have still charged the market value for the car by withholding this information? I'd have assumed that the car was worth less?

I do know that by the mere fact the dealer didn't disclose the vital information that the engine was replaced, in doing so the dealer has committed a criminal offence under Consumer Protection from Unfair Trading Regulations 2008 (misleading omission).

I am just wondering if I should keep the car, if I can get its true part-exchange value on it in 2 - 3 years time or should I avoid the car and put a claim in for a full refund from my credit provider using Section 75 of the Consumer Credit Act 1974?

Thanks in advance for any reply to this question John.
