It's just OK in my opinion.

#1 - You over did it with the contrast, you've lost all details in the blacks. This really ruins the photo in my opinion.
#2 - the blurred background looks chinsy.
#3 - The diffuse glow is just as chinsy - Not my thing.
#4 - You have a VERY tight shot, it's not that complimenting to the car really.
#5 - The background is rather dull and doesn't do much to add anything to the car or the overall composition.

Good luck,

Here's a few that I've done that may add some credibility to my criticisms (before you blow me off entirely).
