Joel Rosen’s east coast-based Motion Performance Speed Shop was legendary for building unbeatable muscle cars in the Sixties and seventies. Teaming up with Baldwin Chevrolet, customers could order a Corvette which would be torn down and rebuilt into an 11.5 second drag car, complete with factory warranty.
One the creations of Rosen was the Phase III GT which made its debut at the International Auto Show in New York City in April, 1969. Motion Performance would build just 12 of the 500+ horsepower grand touring Corvettes with the last one leaving the shop in 1971. That last Phase III GT Corvette was recently purchased from the family of the original owner and has been restored back to original condition and will be displayed at the Muscle Car & Corvette Nationals in November.
