I say you go for the Cobra because of: Looks, Quality, Sound, Power, and because it is made by SVT. Not just an ordinary Ford Engine. The conversations about the speed and power of the Mach 1 over the Cobra got out of hand. The Mach 1's are newer yes. So compare it with the 03 Cobra. I just say go for the powerfull 01 SVT COBRA. I got a 98 Cobra and I say they are awsome.
