Unless I'm mistaken, Power Performance Motor Cars was Power Performance Metal and Chassis/Cobra Specialty Composites when it was owned by the late Mark Doherty (A.K.A. Glasssnake on CC). I believe his sister was on here discussing selling the company after he died in his Cobra. The car was called the Renegade 427. The body appears to be splashed off an Everett-Morrison.
