If you've had your car on scales, I'd like to hear what it weighs. I'll go first:
71 T coupe, no sunroof, with a 3.0 liter 930/16 motor, factory front cooler from a later model and factory sport seats. Also, has a five-speed, sway bars and 15" fuchs. Weighs 2404 lbs.
73-1/2 T targa, all stock, five-speed, sway bars, sport seats and 15" fuchs. Weighs 2442 lbs..
The above are with 3/4+ tank of gas in the coupe, full tank in the Targa. Spare, tools and jack in both vehicles. Neither car has A/C.
The numbers, particularly for the coupe, were higher than I expected. After some digging, I think that they're correct.
For reference, here are the figures from Car & Driver and Road & Track tests. I believe that they weighed the cars themselves, and didn't accept the manufacturer's numbers:
1967 S coupe 2279
1968 911L sportomatic coupe, 2420
1969 E coupe, 2361 lbs.
1972 models: T with 5-speed, sway bars and fuchs, 2425 lbs., E Targa similarly equipped, 2475 lbs., S sunroof coupe, 2455 lbs.
