I totally agree with hsps9.99, your blog is covered in Adsense, which will scare away most, if not all potential readers. To give you an idea, when I opened your blog I was expecting to see info about cars and the first two rows of info offered me "ads by google" promoting mostly Tatoo related ads and Blogger ads. My immediate reaction was to close the site and look elsewhere. If you want to make money, offer info & advice that enthusiasts want to read, Rather than just pricelists and Adsense! Also, lose the font, it appears bold & italic everywhere, which goes against the advice of most usability experts that will tell you to use a clear, concise font that is part of the main families. Sorry if this sounds harsh, but I think you need a severe content and style re-think if you want to make any money whatsoever.
first get more traffic and content, research keyword and then you can make money from any kind as you want.
