As you can see I am confused. I have about 20 grand and perferably below to spend and want one of these 2 cars. I think i prefer the look of the a3 (especially with some upgraded delicious 19" rs4 b7 alloys) but i also love the performance of the the more powerful s4. When I test drove an a3 it had done 6000 miles and was so smooth but compared to my mad bmw m roadster seemed a bit on the slow side, that's why I have started thinking about an s4 as it offers more performance. The main things i wont to know are how much better does a s4 sound and go than a 3.2 a3 and what's the difference in handling. Your comment will be greatly appreciated !
