As previously mentioned, the site is a bit dark and the text needs more contrast to be readable. Perhaps the darkness works well for your target audience. That's an artist decision, that I'm not qualified to make. However, the text needs more contrast for readability. Try a lighter grey for your font. Even if it's one shade lighter, it'll be more readable, yet still preserve the dark feel you're going for.
I love the photos of the cars in the Gallery section, but there's no text with it. Brand, model, year, etc.
Nice cars, I'd love to have one, or two!
