Welcome to the official Motion Performance website. In the old days, we built and sold the most potent street machines money could buy. You can read about them by clicking on the car pictures below. These days, we sell high quality (display) aviation and ship models, and we still sell automotive fiberglass parts. Our friend and webmaster MadMike is a Z28 Camaro owner who started and maintains the Second Generation Camaro Owners Group and is co-owner of Big D Automotive in Cumming Georgia.
