Theres a great deal on a 79 Solar Gold TA in the Forum here. $4900 I got the pics but he is too far away for me to make a deal. Check the cars for sale forum.
I just bought a 80 Turbo TA in very similar shape to the one your posting about since I bought that car last week I have seen 3 smoking deals on Trans Am in better shape! Oh well... I love my 80 but I will have 10 k into it because I paid 5 up front. Getting some dents fixed and nose painted now $1400, Needs headliner, door panels and carpet $1000, got center caps $100 but at least I got to drive it for a week before starting the resto.
