Thanks darijo. Usually I would tackle a car with NURBS, but when I first started looking at reference pics for this car I could see that NURBS would be a nightmare what with all the aggressive shaping on the body panels. On the same note, I didn't use SubD's as I find that the Crease Edge tool just doesn't give you enough control on the look of an edge with an inorganic model. So that left polys.

Hard edges are a pain in polys (each hard edge in this model has 3 to 5 edges close together before smoothing for extra control), but with a little patience and practice you can get the exact edge you're looking for.

Here's a wireframe pic of a Nissan 350Z I modeled totally in NURBS, but never finished. NURBS worked for this because of the flowing body shape. I guess what I'm trying to say is that I never try to limit myself to a particular modeling method, but instead let the model dictate the correct choice.
