Great Customer Service
Our sales person Samuel was accommodating, helpful, made sure we knew all of our options, and made the process so much easier. Sheryl in the back office where I signed all of the new owner paperwork and forms made it so much fun! Great staff. I came there to get a used car because my husband had such a great experience there last year getting his car.
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!

Great service!
Great service! Fast transaction, no hassle. I was completely pleased with my experience purchasing my vehicle with them.
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.

Great Customer Service
Mr. Adriano Silva really surprised us with his excellent customer service! Something you don't get to experience very much anymore. I was extremely impressed with his professionalism. He politely approached us and talked to us before we told him what we were looking for, once he knew what we wanted he went straight to finding exactly what we wanted! That place is full of cheerful people and all willing to help you, no rolling eyes when I asked a question, no interruption while I spoke, overall, it was a great experience!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.
