-The gradient in the menu is kinda tacky, as is the reflection of the logo. The colors are too flat for that reflection to be there.
-There are too many colors. I think things like the find a retailer search boxes should be the same color, and your whole site changes color scheme when you go to car products.
-It seems awfully flashy for how little content there appears to be.
Overall though its not bad, i've seen much worse.
