Hmm when I bought my 04 GT the computer said that shipping weight for my exact car was 3113 pounds.Also when I looked at my GVW I took off 700 pounds for the cargo, 160 or 170 pounds per person riding (total of 4 persons) and my weight was like 3120-3150 pounds empty with a full tank of gas....thats how it said to do it, except the 160 pounds per person, but either 160-170 is standard cant remember, so I did both.Hard to believe that my 66 still weighs less though LOL at 2890 pounds with the tire and everything as well as I believe about 1/2 a tank of gas.
