Shuttle service is so convenient
They took me to work so I could leave my vehicle for service. Great service for the time I have available for the appointment schedule!
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.

Every staff member I've crossed a path with at Shea has
Every staff member I've crossed a path with at Shea has been outstanding and extremely professional! DAMON RILEY in sales made me feel like I truly gained a friend throughout this experience. I highly recommend Damon to anyone shopping for a vehicle. He made the purchase process entirely painless. Advisor GARRETT GIFFORD is extremely professional, very knowledgeable, and patient. I am beyond impressed with how much he truly cares about me. He has made all service appointments completely stress free! The entire team behind the service desk was VERY organized and were familiar with each other's clients. They didn't let any questions go unanswered. It is clear everyone who works at Shea is very passionate and proud of the team theyre a part of! Thank you Shea!
Great car for work!!
Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

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.

Average shopping experience
Overall experience was o.k., we bought a $60k nearly new car, and had it shipped, the car arrived on the transport with less than 1/8 tank of fuel which we thought was a little crappy, the interior was dirty and had scrapes on the kick panels even after we specifically asked about that area over the phone.
Good power very comfortable ride
Good power plenty of room the truck has all kind of new technology in it that helps with driving safety and with job performance Awesome

Bosco is the BEST!
Bosco is the BEST! I arrived with a tire sensor indicating I had a low PSI but I was unable to locate the leak. There was a flat head screw in one tire and a hex screw in the other. I was willing to leave my truck there because I showed up before work and without an appointment. My tires were patched and I was called in less than two hours and I was all set.

We were put in a situation where a truck upgrade was in
We were put in a situation where a truck upgrade was in order, but we didn't want to purchase a new one. Our 2020 SUV was declared "total loss" after hitting a deer while on vacation. Insurance furnished us with a rental car to drive home & to use the following week for scheduled medical appointments that were 1000 miles from our home. Once we returned home, my wife & I decided to upgrade our truck, and not replace the SUV; so, the search began. We wanted a truck capable of pulling our travel trailer and, hopefully, fit in our garage. Not 45 minutes into my search, I found one that I wanted to look at & drive. It was just 7 miles from home! I showed the pictures to my wife, asked her if she wanted to go look with me (knowing the answer), and we headed to the dealership. We met with John, "took the truck for a spin", and returned to discuss details on our trade-in, because we really liked the truck. We had the credit check done; the details of the financing and down payment discussed, and we decided to make the deal. Since we were leaving for Houston very early the next morning, we didn't want to do the paperwork and take delivery until we returned from our trip. We put some money down to hold it until our return home. We've only had the truck four days, but we're overjoyed with it so far. I also can't say enough about the treatment we have received from John and the manager we worked with!
