Complete newbie question, have searched the faq but can't find. Basically, I'm looking at geting an A3 but need to know all the different types, is the 1.8T quattro sport the same as a 1.8t quattro and the seller has not just put in 'sport' in the ad or they different cars!? Same with the 1.8t? Theres loads on the trader but don't know if there's any difference. Anyone help!?
