One of many styling experiments built for day-to-day use by GM styling Chief Bill Mitchell, the XP-700 was built on a standard 1958 283/230 Corvette chassis but received “Grand Prix-inspired” styling cues such as wire wheels, side exhaust and an extended snout, rumored to have been inspired by a one-off Ferrari 250 Special by Pininfarina. After going though a couple of iterations, it is believed that XP-700 was cannibalized to build the XP-755 “Mako Shark” concept car.
