After parting ways with my beloved 2.7T C5, I looks like I'll be getting a black manual S-line 2008 A4 2.0T.

I'll probably have about $1000-$1500 to spend on the car after I get it. In your opinion, what are the best uses for this money? (Either performance or cosmetic)

 

Seems to me the first thing most people do is to chip the car. Will run you about $500 and my understanding is the difference is significant.
