Very clean design and easy to read. It's great how you have the search box upfront and center because that's probably a popular feature for a site like this.
I'm not a big fan of the bright green links on the white background. Kinda messes with my eyes after a day of staring at my screen.

I understand why you chose it. It matches the green in your logo and in the nav but it works better on the black background and not so much on the white IMO.
Oh and your "Car Clubs" link is broken (just in case you didn't know).
Nice job.
