i think that the mach1s will continue to depreciate at the same speed that you have stated for the next couple of years. all the excitement now is on the 05 stangs coming out. look too at the prices on bullitts now. after the 05 excitement (i'm talking general public, i personally don't care for it) wears off, then possibly the values on the machs and bullitts may at least stop depreciating or even go up in value, especially given the limited production, and the seemingly fast rate in which mach1s are getting totaled out, not to mention the fact that they both are great cars.
