wot it said above any help is appreciated cheers
In the first Blenderman Magazin are some car modeling tutorials.
Search the forum to find some more…
Always try wikibooks.com. just search blender 3d then click on the tutorial list link and there should be at least one car tut. onnovanbramm.com has some car tuts, and blue prints. Also try using the car tuts for different modeling programs. If you’ve been using blender for a while you should be able to get the idea from other program tuts.
