Has anyone weighed their GXP Coupe? I weighed mine about 2 years ago on certified (+- 0.1%) truck scales with myself and a full tank of gasoline. The weight was exactly 3100 pounds. I thought curb weight was a wet (oil, gas, etc) measurement with no driver. Remove my 180 pound bottom and it's knocking on 2900. The lowest documented curb weight I can find is from the April 2009 issue of Motor Trend Magazine at 3054 pounds. Did the factory leave something off of my coupe?
