may be u can try search for tutorial about car modeling using nurbs, and learn the basic nurbs modling technique in maya,

ther are few tools i would suggest u to learn for nurbs modeling in maya:
1. using "ep" and "cv" curves and convert to nurbs
2. "revolve", "loft", "planar" and "extrude" tools
3."projecting curves" on surfaces and using the "trim tools"
4. learn how to joint, attach, detach curves
5.using "fillet blend tools"
6. and "non-linear deformer" to bend your nurbs
