Watch it again, I dont think that is a awd Porsch it looks like a GT competition car, Probably a factory preped car, in the neighbor hood of 150-220K depending on when purchased.
No way to tell if it was turbo or awd !

I am suprised and impressed, Think of the cost factor. The Mustang is about a fourth to run!

Also RWD will usually dominate in racing unless its off road or raining. As has been proven time and time again. Porsche AWD turbos retired by the Viper Porsche GT2 Turbos retired by the Viper, Audi AWD A4 in touring car Winners but they faced FWD cars!!! I guess ABT is winning in DTM, maybe AWD will cath up once they lighten the systems. IMHO
