Welcome to Mastercars Company Inc
MasterCars Inc is a company rich in automotive and motorcycling industry experience. We are known as the St. Louis Corvette Kings. Gary & Alex Rosenberger have over 70 years combined auto and motorcycle industry experience. They founded this company with vision of bringing quality, late model, upscale vehicles and motorcycles to the St. Louis Metro East area for a good value with a friendly, low pressure atmosphere.
MasterCars has achieved this goal. We are now an integral part of the Granite City IL business community. We are involved in many regional and local charities. We are upstanding members of the Illinois Independent Automobile Dealers organization, Better Business Bureau (A+ rating) as well as the National IADA.
MasterCars is not a fly by night operation. We are pillars of our local community. We own our buildings and lots and we are always growing. You can stop in 6 days a week, and find a smiling face awaiting you.
