I've been trying to decide what car I wanted and finally did today. I had a nissan frontier and used to own a 350Z, and realized that going from a sports car to a truck was a bad idea so I sold it. The s4 fits perfect, luxurious, nice and fast.

I'm pretty sure I want to get a 04-05 s4 as it seems like its right in the area of what I'd like to spend ($25-30k) and I plan to get a 6MT.

A few questions...

Whats the big differences in the 04/05 models?

What should I look out for when I go to purchase?

Any problems I should know about?

Any other pros/cons would be great. I'm looking forward to purchasing a S4 very quickly!
