Adams had admitted two offences under the Act. One offence was for applying a false trade description to a BMW 525 which Adams claimed had acovered 47,900 miles. The actual mileage of the vehicle was in excess of 141,698 miles.
In the second offence, Adams had stated that a full service history existed for the BMW, when in fact no authentic service history was available.
The prosecution, brought by Trading Standards, was the result of a complaint made by the purchaser, who had travelled from North Wales after seeing an advert for the car in North West Autotrader.
A spokeswoman said: "In this case, Adams has paid the price for falling below the standard of conduct expected of a professional car dealer."
