Well, cosmetically the only obvious issue was the wheels which they could get done trade for £100 all in probably and then a basic service and as said, everyone will say it is "dealer supplied" so the best you can get.
I guess that's always the case and the nature of the industry. How many ordinary punters actually know anything about the history of a car they buy off a forecourt?
If it's shiny and it works, happy days.
I should also add, there is nothing to guarantee that eBay sale went through. The seller may have traded/PX'd it for another at this dealership as they may have wanted to get rid.
