I spent several hours at Serra 9/26 and September 30th Came in to see Monica, she was delivering multiple cars. She offered Nick J to help us Nick was and is superior at his job He embraced our budget and time frame. Showed us several cars. Test drives, car fax, complete presentation. Zero pressure Zero nonsense All very professional. I was at Serra from 10am - 5:47 pm on Tuesday. Got a car Serra honored the price Fixed a tie rod, fluids rotation sent it out to Rite Way Thankful for everything that happened Nick is a Gem. Dealership was outstanding.

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!

We showed up without an appointment, but Ray was quick to help and didn’t miss a beat. I noticed every car I test drove looked freshly washed—maybe just timing, but if he did it on purpose, that extra effort didn’t go unnoticed. He was super honest the whole time, even recommending the used Chevy over a new GMC when he easily could’ve pushed the more expensive option. My car came with a full tank, which surprised me since most dealers leave it nearly empty. He got us a good deal on the plate, found the best rate, and had all the paperwork ready when we came back. The rest of the staff was helpful, and they offered great warranty options. After months of shopping around and talking to a ton of dealers, I’m glad Ray was the one we ended up buying from.
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.

Everyone was inviting and helpful. Charlie Green assisted me throughout the process and was extremely knowledgeable and made everything easy!
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.
