I have a 3D model of a car and some of the normal are wrong.

I can not seem to fix them easily. It is a high poly model so individualy selecting the faces and fixing them is out of the question. I have recalculated the normals about 5 times but still it's not working.

If recalculating the normals via ctrl-n or shift-ctrl-n, on individual linked pieces, doesn't work correctly, you have bigger problems than discontiguous normals. You probably have geometry that is non-manifold in other ways-- zero length edges, doubles, edges joining more than 2 faces, etc. Use ctrl-shift-alt-m in edit/vertex mode, disable non-contiguous on the operator panel, and start cleaning up your mesh.
