Nikki was extremely professional and knowledgeable about
Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!
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!

I met with Dave Fisher, he made me feel very comfortable
I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one
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.

Billy was upfront and personable during the Palisade negotiations. No BS...I recommended him to my son during his Sante Fe negotiation. Billy located and brought in the vehicle he wanted.
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.

Great Service
I bought a 22 Ford Bronco from Clement Ford in December 22 and have had on scheduled service which went great using the valet service they provide. However, what really impressed me was this week I had an issue with the bead locks on my wheels. I spoke to Jerry and Alex in their service department and they were able remove the bolts I was having issues with, allowed me to use the valet service once again, and didn't even charge me for the time. I'm very happy with my experience with them so far!

I felt they were honest 1st of all.
I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

Very pleased with the handling of the sale.
Very pleased with the handling of the sale. Almost no wait time. I did notice on the envelope for the paperwork, that the address of the DMV is incorrect. It, the DMV, is on Zumbhel now not on Raymond.

GM RECALLS ABOUT TO LOOSE CUSTOMERS
I made appt. For recall parts however after making that appointment, and leaving car there for 2 days, was told no parts for repair available. They are available in Florida so it appears I should have had it done there. Bought two cars from this dealer and have always been pleased until now.
There are 20 matching cars close to your year range.
