The Blade is a warmed over Ford GT. Rousch did not allow peter to cut the monocoque so the major body lines remained the same. He filled in the vents this time ( he didnt on the GTM/R ) and produced a different front clip ( fenders and hood). Remember, it was only a 3 month job at Rousch since peter failed to get his "all in house" design completed/started other than a drawing.
In the meantime Peter is AWOL, and it is basically an overpriced Ford GT when the HP2G is not involved. Hmmm, Dodge Viper at 100k or a revamped Ford GT at 200k.. I'm sticking with my Viper.. :-)
