Sam Leman began his career as an automobile dealer in April 1963. Starting with eight employees, he transformed a Roanoke, Illinois, service station into a thriving Chevrolet dealership. At this location, he became downstate Illinois' largest Corvette dealer, selling some 100 Corvettes in 1969.

Sam was actively involved in the business until February 3, 1994, when he died in an automobile accident. The businesses are now owned and operated by Ben and Tim Leman, and their families. The Eureka store spun off to Sam's daughter Beverly and her husband Rich Bertschi in 1994. Third generation family members also became employed by the dealerships, extending the family tradition.

The next several years were spent solidifying our relationships with our customers and employees. Our 300+ employees are constantly striving to continue to be number 1 in central Illinois. Sam Leman LLC continues to focus on being an automotive force to the benefit of our customers and their families.

Our business mission is to achieve customer satisfaction through honest, ethical practices and high-quality service. Our individual efforts during and after work will reflect positively on our business image and contribute to profitability and business success.
