Our Two Service Centers Provide Twice the Convenience

At Gary Lang Auto, not only do we pack together seven dealerships, but we also have two award-winning service centers under one roof. Here you can find mechanics and technicians who are both company-certified and factory-trained, and if all you need are parts we can offer a wide selection that's fresh from the manufacturer. While the service centers might not be open 24 hours a day, their website is, and from it you can research your car troubles and repair timelines, schedule an appointment, and even order parts.

We Love Buick and GMC

Everyone from our sales staff to our technical crew loves what Buick and GMC have to offer, and we'll be pleased to explain what makes Buick and GMC cars, trucks, and SUVs so different from the rest of GM's lineup. We offer every Buick and GMC vehicle available, particularly popular models such as the Terrain, the Acadia, and the Sierra 1500 and 2500. You can also find Canyons, regular and XL Yukons, and even a variety of GMC commercial vehicles such as the Savana full-size van. We don't neglect our Buicks, either, and we have a number of Enclaves, Encores, and LaCrosses all waiting for new owners.

If our massive inventory is not enough, we can still help. Simply fill out what you're looking for in our online Car Finder form and we will bring in just the vehicle you need.
