Baldwin-Motion Performance Group was a marriage of Baldwin Chevrolet and Joel Rosen's Motion Performance, a speed shop. Both businesses were located in Baldwin, Long Island, New York. Starting in 1967 and running through 1974, Baldwin-Motion offered big block SS and Phase III Camaro, Nova, Chevelle and Corvette and Biscayne Street Racer Specials.

The cars were sold either by Baldwin Chevrolet or Motion Performance. They were converted by Motion and delivered as "new car deliveries" by Baldwin Chevrolet. Phase III 427 and 454 cars came with a written money-back guarantee that they would run the quarter-mile in the 11s. Nobody ever came back for their refund.

Between '67 and '74 almost 500 Baldwin-Motion branded niche muscle cars were built for both domestic and export markets. Only ten Phase III GT Corvette cars were ever built, making it the most rare.

Paint and striping on SS and Phase III Baldwin-Motion muscle cars were unique, as was badging and trim. A full range of decorative as well as high-performance chassis and engine options were available. A buyer could order exactly what he wanted on his brand-new Chevy. Popular options included three two-barrel Holley carbs, Phase III CD ignition, Hone auxiliary overdrive transmission, scopped hoods, mag wheels, etc. Except for demonstration cars that were sold periodically, all Baldwin-Motion Chevy cars were built-to-order and could be powered by big-block engines ranging in horsepower to over 500. Baldwin-Motion never rebadged the COPO 427 Camaro or Chevelle. Unique product catalogs were produced in 1968 and 1969 and today they are rare and collectible. During the early 1970's they were included in the large Motion Performance mail-order catalogs.
