Might I suggest, having just had a look at your last post, that you work at keeping your paragraphs quite a bit shorter - it makes text much easier to read on the screen. I know, I don't always take my own advice, but mostly I do.
And, as TT says, writing is what it's all about - get your stuff out there, properly tagged and categorised - heed what TT says about that. If it's well-written, and interesting to a wide-enough segment of society, people will read it.
And those two points are vital - no matter how perfect your tags and categories are, quality and content are the biggies. See http://ronsrants.wordpress.com/2009/12/26/attract-visitors-to-your-blog-first-step-write-one/
Just bear in mind that, by writing about cars, you've chosen a very heavily-subscribed subject - i.e., you have a huge amount of competition.
Unlike baseball fields, "If you build it, they will come," doesn't apply to blogs. Just being there isn't enough - you have to make your presence felt. Give people what they want to read, and they'll come. Just not right now.
