Originally a gas station and small car lot, Cliff Mills Motors Limited opened its doors in 1938 at the southeast corner of King Street and Park Rd. in Oshawa. The first vehicle ever sold was a six cylinder Willys Coupe for $139! That was over 70 years ago. Today, Mills Pontiac Buick GMC is a multiple award winning General Motors dealer that is among the largest vehicle retailers in Canada. Its world class 55,000 square foot facility boasts Durham Region's largest vehicle sales showroom and employs more certified Grandmaster technicians than any of its competitors. While the old gas pumps are a memory, what has endured is the company's deep commitment to its customers, employees and to the community.
