New and used 2026 GMC Terrain for sale near Davison, MI

Every staff member I've crossed a path with at Shea has been outstanding and extremely professional! DAMON RILEY in sales made me feel like I truly gained a friend throughout this experience. I highly recommend Damon to anyone shopping for a vehicle. He made the purchase process entirely painless. Advisor GARRETT GIFFORD is extremely professional, very knowledgeable, and patient. I am beyond impressed with how much he truly cares about me. He has made all service appointments completely stress free! The entire team behind the service desk was VERY organized and were familiar with each other's clients. They didn't let any questions go unanswered. It is clear everyone who works at Shea is very passionate and proud of the team theyre a part of! Thank you Shea! 

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

They were very professional and responsive. They answered all my questions. Response was very quick both through SMS and email.

Everytime I?ve been in the dealership I get the respect I want as a woman. This is the absolute best place for price and service

I can’t say enough about the Shea Team from there car salesmen to there finance department, they honor in doing there very best to get you in what you’re looking for. I dealt with Nate Brown personally and he was excellent, very professional, and easy to work with! Get an appointment with him you won’t regret it!

My experience with the company is always professional, polite, consistent, and concerned about the needs of the customers. Howard does an amazing job in assisting with problem solving in order to get the best results for the service provided. By initially going above and beyond the call of duty for not just me but all of his clients / anyone who may need help.

Lance was great! He listened to what we wanted and delivered. He juggled multiple clients with no interruption to our service

Even though we didn’t buy from Shea ….Aaron was great to work with nice guy, absolutely no arm twisting.. thanks for having some good people at your place .

They were great, called me right away, very curteous and no sales pressure. It was the car I've been looking for but its 2500 miles away so i passed.

Tony Hauck was absolutely the best car salesman I’ve had the pleasure of working with. Instead of giving the typical car salesman scripted approach, Tony listened and made the whole process very quick, easy, and comfortable. Although we have to pass multiple other GMC dealers on the way to Frankenmuth, we will gladly make the trip again due to Tony’s excellent support and service.

I always feel like I?m appreciated and respected at this facility

I went to Shea Buick GMC because their inventory of preowned vehicles had many selections of the models that met my needs as far as mileage, year of manufacture and price. I actually bought the vehicle I had been the most interested in since March. I made an appointment, the salesman met me at the door and had the vehicle I was interested in with the air running ready for a test drive. It was perfect! We added a tonneau to the package, agreed on a price for the trade-in and the purchase price for the truck I bought. We arranged for the insurance, the installation of the tonneau and for a pick up time at my convenience. All was done in a matter of 2 hours! Everyone I worked with was kind, focused and professional... the efficiency of the transaction speaks volumes to the dedication of Sheas' staff!

Took my 06 Hummer H3 that had front end damage to Mike Young bodyshop. Mgr Mike Bragg gave me a loaner while repairs we done. Parts were hard to come by because of the Hummers age. Mike & staff worked diligently in getting the right parts. My Hummer looked excellent when I got it. The staff is professional and courteous. For years our family has leased and bought from Mike Young

Outstanding . They go above and beyond in the repair department. My Acadia looks brand new . They cleaned the inside , even scrubbed the floor mats . I wasn?t expecting not expecting that so it was a lovely surprise.
