Pontiac Firebird 1967-2002 - need help with selecting a new T/A

I just found a buyer for my 99 Z28 A4. I sold my Camaro because I decided I wanted to upgrade to a newer 01 or 02 T/A M6 (WS6 or Firehawk) with much lower miles than my Camaro has. Besides any obvious blemishes the car might have, what do I need to look for or check when selecting the T/A? Anything on the body or the internals that typically starts going bad that I can check for and so forth? Thanks for you help.

headlight motors, otherwise everything is the same as the Camaro mechanically.

thanks for the info. man. I will be sure to check those before buying, and make sure the seller fixes them or reduces the price accordingly if they are not working.

Cracked door panels.
B-pillar or sail panel bubblling.

On another note, ..., What is "CBE" in yer sig?!?

CBE is Cat Back Exhaust.... but now that will be for the new owner to decide... He told me that he was not going to mod it, but just drive it on the weekends.
