I just bought a new 2026 GMC terrain Denali from Astria. The sales rep was excellent. The sales manager was excellent and the business manager was excellent helping me get my car on time. I highly recommend this dealership even though it was an hour and 40 minute ride it was well worth it. Thank you Syed Ahmed for the outstanding job.

My son and I had a great experience at Mastria GMC. Nate the sales manager made our experience comfortable and stress free. He had a great personality, was knowledgable on his inventory and was not pushy at all. We then dealt with Marsh in the finance department. Also a painless prioress. She explained all our finance options clearly and didn’t push us in to any overpriced plan. I would highly recommend this dealership

I want to share a recent experience my wife and I had with Mastria Cadillac. We were on a road trip with our new electric Optiq Our planning left something to be desired and we were scrambling for a place to charge up quickly. We stopped at numerous places (including other GMC dealers) that didn’t have chargers or their chargers were for customers only. We finally landed at Mastria. The people there were great. Friendly and accommodating. They moved some vehicles and got ours changed. We were back on the road in 30 minutes. Thanks to all, especially Sayed Ahmed. Five out of five stars for these folks!

Going to Mastria was a Homerun. Shopped around within 100 miles from my house and found Mastria to have the best prices, and I’ll add it was a very easy, relaxed process from start to finish. Best salesman by far in all my years of buying vehicles is Sayed Ahmed. Honest, knowledgeable just an all around good young man. He’s employed by Mastria but works for you! Highly recommend Mastria, go in and ask for Sayed.

I felt like I had to write this review as soon as I left a lot. My experience at Mastria GMC was exceptional, even though I didn’t purchase a vehicle at this time. As soon as I walked into the facility, I was greeted by two gentlemen who helped me through some questions before handing me off to Nate. I was looking at a new 1500 and had some questions about it and wanted to take it for a test drive. Nate was super knowledgeable, extremely nice and we had a good conversation about the truck. When I am ready, I will be returning to Mastria GMC to purchase my truck. Thank you for excellent customer service and not being overly pushy like other dealerships.

Service Department is great!! I mistakenly show up a day early for my afternoon appointment and they without hesitation started to figure out how to accommodate my early arrival. They told me if I was willing to wait maybe as much as two hours they thought they could get me in and fix my electrical issues. While you bet I was very happy that after about 30 minutes they came and got me letting me know everything was fixed. I was extremely pleased, though I will never make that mistake again.
