Hi there,
Well I can't really say I'm overwhelmed by the style but it definately suits your content. The car in the top right works well. There's a few jagged edges on some of your buttons too. You might want to try and fix that

Also your buttons, they look good but IMO need a little tweaking. I'd smoothen the bevelling a little and instead of adding a big drop shadow like you did. I'd try a 85% opacity 1 pixel drop shadow and that will make the white stand out a lot more on the gray.
Best of luck with your site
