About DeMarois Automotive


DeMarois Automotive has been family owned in Missoula since 1958. Originally “Turmell DeMarois Oldsmobile of Missoula”, Robert G DeMarois partnered with Fred Turmell, and eventually purchased the business outright. GMC was added to the dealership in the early 1960s, and the business eventually added the first Mercedes Dealership in the state of Montana in 1980. Formerly located on main street in downtown Missoula, the business eventually moved in 1982 to the current location on West Broadway. Since then, the business has remained family owned and operated, with five siblings continuing to run the business today. We take pride in being locally owned and calling Missoula home for over 60 years. We look forward to serving you and your family for any of your automotive needs, and our commitment is to always treat you honestly and fairly.
