Hi all, looking for a little advice. I am looking to buy a second hand A3 170bhp S Line and not sure if I should go Quattro or not. Probably 56 or 07 plate with between 55-70k miles on the clock. I will probably do c.12k miles per annum. Is Quattro worth the premium and also, are there any key faults/questions I should be asking? Probably be a non Audi dealer where the A3 will be purchased. Thanks all!
