At Coleman Buick GMC Cadillac, certified technicians combine advanced technology with good old-fashioned GM parts to maintain GM vehicles, as well as other makes and models. The crew employs computers to ensure wheels are aligned properly before making any necessary adjustments. They swap out old oil and filters for new, rotate tires, and check for signs of unrest among the ranks of hoses, belts, and clamps. Brake, power steering, and transmission services are also available. For customer convenience, all appointments can be made online.
