sorry, but I think it's a great idea to target just one car/keyword. little competition so more likely to get visitors. I like the site.. but I would suggest you put adsense on the front page above the posts too.. if you're trying to monetize with adsense. Stuart
Your website is looking good with a classic theme.. The pics are really cool and i would suggest you add more content about the features of the cars so that people would get to know more about it.. Hope you know about SEO, keep working on that.. Good luck!!!!
nice site but looks a bit bare...improve the layout a bit...maybe a more spectral color scheme. (if that is even a word). I mean the yellow and red cars, and red background...thats all the colrs u have..find more complementing colors to make it look more professional/good
