Transaction was great and employees were very patient and professional! Thank you so very much!
Great Diesel truck when emission sensors work
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.

Used car purchase
Jeff B was professional, personable, considerate and everyone from start to finish did an amazing job, I am excited to be in a newer vehicle and the ease of the buying process was wonderful, so far a great experience, thank you.
Great luxury ride with great pulling capabilities.
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.

Love how the Service Department takes care of my car! They are fast and make suggestions that really help me plan to prevent issues. The staff is courteous and helpful, always checking in on me while I wait in their comfortable lounge and they keep me in the know if something comes up. I have had great experiences each time I have gone over the last two years for service. I will know where to shop when it’s time for a new car!

Keep the old girl running.
Bottom line cost hurt but with over 100,000 miles and a great service rep (Carry) I understand. Like the way you flag upcoming needed repairs. It allowed me time to budget them in. Five star all the way.

The service met what i needed.
The service met what i needed. I was able to ensure that the price of the repairs that were needed were affordable and correct. I just wish some of the future repairs that are needed are more affordable and could be more explained by the customer service representative like the previous rep that I had at the previous visit. Overall, the facility was very clean and i was able to meet with one of the car/service representative. I was able to meet with a car dealer who was very friendly and ensure that I had his contact information, in the event I plan or may want to purchase a new vehicle in the near future, which i plan too.
