2026 GMC Terrain Denali AWD

Groulx Oldsmobile is the best place to get repair work done on my vehicle. I won't take it anywhere else. They're extremely professional and knowledgeable, and they always take especially good care of my car. They're very friendly and polite. Their automotive shop is the cleanest I've ever seen.

CHRIS, Service Dept Boss, was 1st class! I care greatly about my truck, 19 mos old, and only 1700 miles. He and the techs treated it with the utmost care. I waited in waiting area, and was very comfortable. I plan to return Groulx often for service and future new car purchases. Nice job Chris! David Whitaker, Monroe,MI.

I purchased a used truck from Larry Montri. He and his sales team are amazing going above and beyond any expectation. I got a fair price for my trade in and the same for my purchase. I'm also from out of state and they did all of the inspection and title work for me. Which means when it came time for me to get plates in my home state, it was a breeze. Thank you for an excellent experience.
