For more than 70 years, Mills Motors Buick GMC has been the greater Oshawa area’s dealership of choice. Originally founded as Cliff Mills Motors Limited in 1938, the very first car sold off the lot was a Willys Coupe for the price of $139! A lot has changed since then, but much has stayed the same. We have become one of the largest single vehicle retailers in all of Canada by putting customers first. It was a priority on the first day of business, and it continues to be a priority today.
