I had a 96 TA before my 02 TA and there were differences, but to my surprise, I saw a 97 with some of the features I thought GM saved for the new models. My 96 had a wobbly center console that opened from the front, where the 02 has a side opening one, and it was more sturdy. They put drink holders for the back seat passengers and that famous passenger side cupholder that folds out from the dash. But again, I think those were available from 97 up. Also, digital mileage, instead of the rolling odometer. Now my 96 was cloth and the 02 is leather so I don't know for sure, but the sides of the seat have a ridge design on the composite part. Other than that, I think that's about it.
