Well I hate the colour of my Bugatti, but I cannot imagine what I would have that would interest you in trading. I'm only level 28 and cannot be bothered to game the game (dupe, birthday trick or the like). Maybe there is something really simple you need, like another BMW 2002, plus a couple French cars to replace the Bugatti hole that will be left?
Maybe you want an ugly Bugatti. It's kinda teal and silver. Cannot check colour right now as my Bob is grinding me some dough with the Furai.
