I removed the background. I dunno, might look better. If I might make a suggestion on placement, I think it would better if it were placed down a bit and further to the right, so it is more or less centered between the right edge and the end of the navigation bar.
The right back end area looks a bit chopped off, it was hard to tell though where the car ends and the background begins. Oh well. Do with it what you want I guess.
EDIT: You know what? I think I can fix that. So don't use this just yet, I will post a better version of it so it has the back end part better and is not so flat there.
