Hi all! I've been eyeing this vehicle from an auction list for several days now and I am completely stumped as to whether this car is a 2003 b6 s4 or an a4 spec-d out to look like a S4.... The information available on the vehicle is limited other than these pics I've received, thanks in advance!!

 

I Owned a 2002 B6 A4, and just purchased a 2005 B6 S4. The seats are from an S4 without The Recaro's. The front bumper has is That of an A4, the trunk wing is that of an A4, the steering wheel looks to be that of an S4, however, the A4 did come with that kind of steering wheel as well. If I had to guess, it is an A4 speced out like an S4. Unless for some reason, the person who owned it decided to downgrade the S4 components to A4 components. Which is possible. I am guilty of this myself, as the parts for A4's are commonly FAR cheaper than parts for the S4. Even in the aftermarket world. What will really tell you if it is an S4 is pics of the engine. If it doesn't say 4.2 (the only engine that came in the B6 S4) then it is an A4.
Hope this helps!

 

A4. No engine specs are listed? Run away!

 

Looks like a B6 A4. It has A4 side mirrors, A4 door sills and A4 manual seats.
