This is my '97 M3.  There hasn't been too many modifications done on it yet.  Surprisingly I like it just the way it is.  My '97 328is that's posted got a bunch and even the 540i (posted as well) got more.  This are great cars out of the box.  Here is what I have done so far

 

-HR springs

-Magna Flow Exhaust

-Painted the whole top of the car Artic Grey (rest of car artic silver)  Why??  Just to be a little different

-The wheels came on the car, but eventually will be changed out

That is it so far.

-This past Concours it took 2nd place right behind the same guy with his silver 328i that always wins.
