unless its a signed edition shelby yes the price is too high....you never pay a premium for a clone.
so if its had a shelby package....what's in the package:
-supercharger & how much power is it running?
-suspension & chassis upgrades?
-short throw shift
there should be a build sheet outlining all the details of the package, and until you have that information hard to understand what the value of this car is.
once you have details of the build you can cost out what they would be if you bought a stock NEW Gt and did the mods yourself
you are better off buying a stock gt and doing supercharger/exhaust upgrades.....
here's genuine item...500hp shelby
