Gas Is pretty heavy and would explain some of the differences I can't remember anyone weighing the car with the light on.
57/43 weight distribution but that's not surprising. The bulk of the weight loss is in the rear of the car. With some lighter wheels and tires and a muffler delete pipe you could get awfully close to 2600 lbs. I was shooting for 2650 in my limited. There is a good 6-7 lbs if you drain the washer fluid.
Of course I could probably stand to lose a few lbs myself.
