Looks good. Your geometry is nice and clean. Looks a little too
smooth though. Maybe try adding some ridges/definition around the lights and scoop in the doors. Of course, I've not seen the car in person though so maybe that's the look you're going for. If your still looking for a way to create the rims; try creating the curves in illustrator and then importing them into maya and using bevelplus. You may find it a little easier too create them in Illustrator. Here's a tut for it: http://www.digitaltutors.com/digital...ideo.php?v=588
Also, Cut Curve is located in Edit Curves/Cut Curve
Basically, if you grab two curves and apply the tool it will cut them wherever they intersect.
