The original Baldwin-Motion Performance Group (1967-1974) represented a partnership between Baldwin Auto Company, a franchised Chevrolet dealership dating back to the early-1920s and Motion Performance, a high-profile speed shop with a reputation for building fast Chevys. Both were located in Baldwin, Long Island, NY, a New York City suburb.
Starting in 1967 and running through 1974, Baldwin-Motion offered SS (425-hp) and Phase III (500-hp and up) big-block Camaros, Novas, Chevelles, Corvettes and Biscayne Street Racer Specials. Cars were sold at Baldwin Chevrolet or Motion Performance, converted by Motion and financed and delivered by Baldwin. Phase III 427 and 454 cars came with a written, money back, quarter-mile performance guaranty from Joel Rosen.
All Baldwin-Motion sales promotion materials carried Rosen's guaranty. “We think so much of our Phase III Supercars that we guaranty they will turn at least 120 mph in 11.50 seconds or better with an M/P-approved driver on an AHRA or NHRA-sanctioned drag strip. Phase III Supercars are completely streetable, reliable machines that will run these times off the street.” There never was a single comeback!
In July, 2005, Joel Rosen and Marty Schorr, the people responsible for the ground-pounding, take-no-prisoners Baldwin-Motion 1967-1974 SS and Phase III 427 & 454 Chevrolet Camaro, Nova, Chevelle and Corvette specialty cars, formed an exclusive strategic business partnership with Joel Ehrenpreis and Larry Jaworske, MOTION, LLC, Sarasota, FL. The mission: Re-launch the Baldwin-Motion and Motion brands and create and market the Great American Supercar. In addition to coachbuilt-to-order, limited-edition Baldwin-Motion supercars, MOTION, LLC planned to develop a line of Motion-branded high-performance products. The Launch Edition of the Great American Supercar project was a new, highly sophisticated 1969 Baldwin-Motion Camaro SuperCoupe, powered by a 600-plus horsepower fuel-injected, all-aluminum 540-cubic-inch Merlin/Motion big-block built by Bill Mitchell.
Baldwin-Motion disappeared again in ~2016.
