First off: My Camaro tutorial sucks. I would suggest using the Honda
one instead, it's basically the same thing but a different car. I dunno how much better it is, but it is better than the Camaro one. I need to get rid of the Camaro tutorial, but for some reason every time I convince myself to remove it, I don't...I apologize if it has run you astray.
I would say it sounds like you are okay so far, you just need to give it the third dimension as Brektzar stated. That is, unless we are misunderstanding the problem.
