Granite Buick GMC

5/5 Stars - Fantastic Experience! We recently purchased our new GMC Sierra 1500 Elevation Duramax Diesel, and we couldn't be happier. Because we took our time and went through each step of the process slowly and methodically, it was a long journey—but the dealership team made it a seamless and highly professional experience from start to finish. A huge thank you to Marcus Mack, Cole, and Paul. All three were incredible to work with, completely patient with our pace, and instrumental in helping us achieve our goal. Our new "Silver Beauty" is exactly what we wanted, and she is going to do quite nicely for our future long-distance travels and towing our camper. If you want a team that respects your pace and delivers top-notch service, this is the place to go. Thank you all so much!

Jose Familia did an amazing job finding exactly what I needed for my family and I! He made sure it had all the bells and whistles and for right in my price range! Felt right at home and left one happy customer! Best experience! Thank you Jose and team!

We experienced some technical issues with our Hummer EV while traveling and arrived at Granite GMC for assistance. Josh Wagner provided outstanding customer service. He quickly diagnosed and fixed the problem, arranged a shuttle to a nearby restaurant while the repairs were being completed, and even delivered our vehicle to us afterward. We are truly grateful for his professionalism, kindness, and commitment to customer care. Thank you, Josh, and the team at Granite GMC, for turning a stressful situation into a positive experience during our road trip.

I recently purchased a Ram TRX from Granite Buick GMC, and I can confidently say it was one of the best car-buying experiences I’ve ever had. From the moment I called from Texas, Jose Familia gave me his full attention. He immediately sent multiple videos of the truck, answered every question I had with patience and detail, and made it clear that he genuinely cared about me, not just making a sale. Thanks to Jose’s quick responses and professionalism, we were able to get everything done in just one day. I flew in the very next day and was warmly greeted by several members of the staff. Jason in finance was equally amazing—he took the time to walk me through everything without any pressure or confusion. The entire process was smooth, transparent, and stress-free. Jose deserves huge credit for making this happen. I had been considering TRXs across the country, but Granite beat out the competition with great pricing, military discounts, and even better service. I didn’t just get a fantastic truck—I got to work with genuinely good people who take pride in what they do. Whether you’re local or shopping from a distance like I was, I highly recommend giving Granite Buick GMC a call. Great dealership, outstanding service, and most importantly—incredible people.

We were out in Rapid City on vacation and came across a truck that we really liked. The price was fair and our trade in price was fair. Marcus Mack was probably the best salesman that I have ever dealt with. He went above and beyond to help us. The bad: We were told the front brake pads would be changed prior to us taking ownership. After having the truck for a couple of days, I couldn't reset the pad life so I called Marcus. He then relayed onto us that they hadn't actually replaced the pads because they were not worn down enough, even though the service manager told us directly that the percentage worn was not what they let their vehicles off the lot with. We bought the extended warranty and Jason informed us that the when the truck comes out of their shop, it's just like a factory reset. 6 year, 60,000 mile warranty. The guys in the shop didn't change transfer case fluid even though it was due according to the maintenance schedule. Now I have an expensive warranty with a transfer case that may or may not be warrantied. We bought the Cilajet sealer last minute. Jason assured us that the detail team would have time to do this. This took a little longer than expected but it was our decision to do this. With it taking about 4 hours, my expectation was to have a very clean vehicle. Most of it was good, except the cup holders and the entire driver side of the engine wasn't cleaned. Overall, I would recommend buying a new vehicle from Marcus. I would not, however trust them to do any maintenance work on a used vehicle, even if they tell you they are going to.
