1976 76 Pontiac Trans Am 400 v8 , 2nd owner Transam Firebird

1976 Trans Am, 2nd owner, all paperwork from Original Owner. Rust issues due to the car not used for years. Car would run and drive until parked, engine turns over and never been changed nor modified. The transmission was working fine, also till it was parked. All grass is good.
Have several pics of the TA. Floors have only surface rust with a minor rust hole. Tore carpet out to inspect. Original quality new Carpet in the box that goes with the sale. Trunk floor has rust and bent in rear, needs replacement.
Doors in condition. Space savertire, never used. Original wheels. TA is basically original. I never replaced anything but tune ups! Frame looks good, only surface rust. Will provide pics of your concerns, if you will contact me through Ebay.
