How much more is the gta worth over the non gta stang that year? What were the options that came with the gta?

 

Basically not worth any more than a GT (A is for automatic).
Some people feel the autos are worth less, but the GTA designation was only put on for that one year I believe.
It is probably worth more than the $5k current bid, how much more depends on condition and how badly you want the car.

 

The main concern is rust. The places to look are the chassis, floor panels, doors and fenders. If rust is present behind the kick panels it means the cowl is rusted and will need mayor and costlly repairs. One way to tell is by pouring a couple of gallons of water on each side of the cowl. If it leaks it will show on the front carpet soon after.
