according to the office of fair trading its a breach of several regulations for a used car garage to mislead a consumer, and it specifically gives the example in its guide about a garage selling an ex driving school car as a one owner car.
You could understand if the dealer did not know because the pedals had been removed before the previous owner traded the car in, but they removed them !!!
The salesman even said to us they took the trade in from a local man, and he said its one owner which is always a good thing........
I should really post the reg on here so none else gets caught out, i very nearly did
