Friend of mine ordered a 2013 Gt500 and is selling his 93 Cobra. I am interested in the car but don't want to pay too much for it. I know mustang but wanted opinion from some 93 enthusiasts. He is the original owner, car has 55k on it. Black with gray leather. Edelbrock heads, ecam, suspension upgrades, kenny brown street cage. Car had a high end repaint in the original black with min grey stripes. I know the car would be worth more stock. Any opinions on wha it is worth?
