Baldwin-Motion is a legendary name as it represents some potent dealer built supercars from the American muscle car era. Invoiced as new and complete cars, these cars came with a warranty, and could be ordered by mail. Joel Rosen was the defining personality of Motion Performance Products which were sold through Baldwin Chevrolet of Long Island. His engine of choice was the L-88 which he installed in several Camaros, Corvettes and Chevelles. What separated Motion Products from its competitors, was not only a guaranteed 1/4 mile time, but radical styling packages which usually included distinctive stripes.
In 1969, Joel stripped down several big block Corvettes to create his Corvette Phase III GT. The Phase III Corvette received a comprehensive tuning program which more than doubled the cost of the base model. For reasons unknown, Phase I or Phase II were never offered. Easily identified by their fixed headlights, only ten of these were lightweight Corvettes were made, and no two are identical. Custom exterior features included: recessed headlights, functional hood scoops, custom side louvers, slanted rear windows, Dodge fuel fillers, slit taillights, motion traction bars, custom side mirrors and flared wheel wells.
