The front seatbacks were flat and not contoured. From 1983 onward, the backs curved inward a bit for better rear legroom. Also, there was an 85 MPH speedometer, loop carpeting instead of weave, and the front dome light on the 82 models has a smaller switch and no separate map light function. Also, the vanity mirrors don't light up on the 82 models, and the driver sun visor doesn't have a mirror. The mirror on the passenger door is not power controlled either. That's all I remember off the top of my head.
