Since my Forza 3 screen shots were deleted ive decided to post my concept drawing of the designs that eventually ended up on the cars.

Here we start with a BMW M3 which i drew for  coyote_snack This is the front view with modified headlights featuring LED rings instead of the halo rings as well as visible intercooler

I like how it came out and BBF himself liked it too!

Forza Morotsport 2 version of this car is on my DA
