Raced a 96 cobra at a drag strip in holt. He had exhaust and slicks and he could only pull a car on me out of the hole and we stayed at the same length all the way through the 1/8. This is when my car was completely stock with S rated tires.
I'd spend the money on a 99+ GT if u you wanted a stang. You could get one for about the same price as a older cobra..
