Maybe a BMW M3 race car? It has a lot of miles though
I also have Lambhorghini Countach, Ford GT, and Toyota Ft-86 Concept
Anything you particularly interested in?
I have an 08' Premium Calsonic Skyline GT500 car and the Total livery Peugeot 908 (black/blue) for trade for the Sauber C9. Have a trade slot open today until 9PM EST. I also have a Mugen NSX JGTC racecar (standard).
EDIT: Found a C9 elsewhere and traded the Calsonic Skyline. Mugen NSX is still available. Would be interested in the R89C.
