Ian Graves, of Southcote, Berkshire, breached an injunction stopping him selling cars without telling buyers he was a dealer in classified adverts. Graves, already in jail for handling stolen goods, was given another six months in jail by Reading Crown Court for contempt of court.
Graves claimed he had misunderstood the injunction, served on him following a two-year council investigation.
He used to park cars with a ‘for sale’ sign and a phone number along a main road.
In court, Graves said he was not a trader because he made no profit on sales and that cars were just a hobby.
Trading standards officers said Graves put 13 adverts in the Thames Valley AdTrader that did not make clear he was a dealer.
