My boss just picked a GXP up on Tuesday. I was drooling. Funny thing about those wheels. You can see an ALCOA stamping on the wheel. My boss's neighbor works for ALCOA and said that GM let them put their brand name on the wheel because ALCOA did not charge them to stamp "Forged" on each wheel. I'm not sure why they would want that on the wheels. I heard that by doing that for them ALCOA saved GM a $1.00 per wheel.
