I'm not a modeler of cars but it looks good so far (I don't know what is going to be done to the front end so I didn't count that), though seems more tutorial-sh and than W.I.P. Plus you're already a good ways into the modeling for you to start a topic without at least giving some progress upfront, it leaves the viewer to follow a link where they have to play catchup and that may turn off some people, so my advice is to post some key shots here and then go from there.
