Damn Jim thats a really nice GTA...the fact that its a 91-92 that clean, has ttops and what looks like to be an original non cracked Aero wing....id say you can get at least 2 grand for it. List this bad boy on LS1 related sites...this is a perfect candidate for a swap honestly. If you held out you can probably get 3 for it from the right buyer, especially if the ground effects arent cracked at all
