I just purchased my 4th Truck from the Glendale store . This is the 4 truck in 6 six years. The staff does NOT get any better then these folks. From the warm and inviting welcomes to the store to the Superior Management. These are the best people around and I can't thank the enough. I am a customer for life. Thank all of you Sincerely Dan Hubbell

CarMax TulsaReviews
CarMax Tulsa review
Of four offers on my vehicle CarMax was the best, the looked at my vehicle and the final offer was exactly what the internet offer was! It was a simple process. They issued a check on the spot and made us very comfortable. Thank you carmax!!! Best part was the other companies all reached out after the deal was done saying we could beat that deal…..guess y’all should have tried not to lowball up front. I definitely will do business with them again
2020 GMC Sierra 3500 review
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Scott Litton was very helpful, knowledgeable and efficient. This was the best truck buying experience we have had. Finance was a breeze. I would definitely recommend this dealership.
2020 GMC Sierra 3500 review
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Jerry Seiner South Jordan GMCReviews
Jerry Seiner South Jordan GMC review
Initially my wife and I had just planned on purchasing a car for her since the lease on her current vehicle was due to expire. Chris Warr was the sales consultant who helped us when we arrived to test drive a few different models. My wife wasn?t really sure if she wanted an SUv or a truck. Chris was patient and friendly. He made us feel comfortable and not rushed to make a decision. He even went as far to take us to see a model that was being displayed for a car show so my wife could see all of her options. Ultimately she purchased a 2026 Terrain AT4. Every one we encountered was friendly, helpful and answered our questions and made the process of purchasing a car simple and as stress free as possible. I would like to mention Ben Gallegos for helping us with the additional accessories my wife wanted. Marian Ciubotaru for walking us through the financial side, he answered all of our questions and took the time to make sure we were clear on the paperwork and pricing. Frank Pereira was our initial contact when we scheduled our appointment. He was friendly, listened to our needs and stayed in contact through the entire process. We are definitely happy with our interactions, so much that I had an appointment the following day to purchase a Ford Bronco for myself and ended up canceling my appointment and purchasing a Canyon AT4X the following day. So 2 car sales in 2 days. All due to the treatment we received and to be clear feeling comfortable and not being bombarded with a heavy hand to make a decision until we were ready. We also believe we received a fair deal. In addition, I was not happy with the rims on the truck which was almost a deal breaker for me. Purely because I had a vision of what I wanted. Ben, Frank and Chris worked to find me options and Ben found the exact rims I was looking to purchase. We are taking both cars in on Friday for the accessories and they even made sure we have a car to drive while our new cars are being completed. We are grateful and not only will we be buyers in the future we will be sure to share our experience with our friends and family.
