I had an outstanding experience working with Ty on my recent vehicle purchase. He was consistently responsive, knowledgeable, and never pushy throughout the process. We don’t purchase new vehicles often, but when the time comes again, I will certainly return to Ty. I highly recommend him to anyone looking for a straightforward and positive buying experience.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Ms. B
Excellent, from the day I walked in to finance my truck every member from Sales to Finance were 100% committed to the sale. My process was hassle free
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?
