My decision factors for going with blower on the GT;
Candy Red not available in GT500
Automatic not available in GT500, yes I like the auto...
GT500 twice the price, even if I got out of my GT clean my payment would double.
Blower on the GT would have similar or more power, and get better MPG.
The big negative for the GT is the lack of warranty unless you go with FRPP, Roush, or Edelbrock warrantable (lower powered) configurations. Plus, it still is just a GT with a blower versus a GT500.
To a lessser degree this would be my daily driver and it seems a shame to put all those miles on a GT500.
In the end I just could not overcome doubling the payment.
