I was looking to get one of these cars, its my favorite audi, i love the shape of the 90. If i were you, i would get a 88-91 version with the 2.3 5 cylinder, that way you can swap a 2.2l 5cylinder turbo in pretty easily. And the V6 in those cars is only 12 valves, compared to the 30 valves in the later versions, and personally i prefer Audi 5 cylinders, cuz there classic, just like BMW sixes.
