It was my first visit. It was just for a factory recall, but I could not have been treated better. A very positive atmosphere and everyone was so courteous. I will be coming back!!!

Always a great experience going to this service department. After decades of sub-par service attentions, this is refreshing. The restrooms and waiting area is the cleanest I have ever seen and the Service Managers are great!

I’ve been a customer of mark Allen before this new vehicle and it’s a great company. They will try their utmost hardest to get you into a good vehicle. Brian was a FANTASTIC salesman, he went on the test drive with us, very detailed instructions on how the car runs and all its special equipment and components. They gave us an amazing deal that we couldn’t resist! I’m so glad that we chose them and chose our brand new 2026 gmc terrain AT4 it’s a beautiful suv for a newly married couple thinking of kids!

I won’t be back. I gave them several chances. Always feel disrespected by several members of the staff.
