Excellent info, thanks. Seems like there seems to be quite a bit of variance in the weights, though, maybe from scale inaccuracies?
That 4,000lb 1996 TA must have a lot of stereo equipment in it , be a convertible, and/or be with the driver in it. My 1996 LT1 automatic was 3,580lbs full (full gas, spare in, etc..) w/ me NOT in it. This was on a CAT scale which apparently is certified (I have no idea what that exactly means, though). My GN "seemed" like it felt lighter than the LT1 TA, perhaps even lighter than the LS1, so I was guesstimating the TR to weigh about 3,400 (full, w/o driver).
