Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Out of state purchase
Great experience. They went out of their way to accommodate me as I flew in to finalize the purchase. I was picked up at the airport and returned to my hotel later. They cooperated in arranging to transport my purchase out of state. First rate experience. Can't say enough about how pleasant they made the experience.
I have owned this gmc since 2000.
I have owned this gmc since 2000. I drive it every day and have not had any issues with the truck. She has almost 500.000 on her, she doesn't use any oil runs great , the engine is 95 % original, transmission is original. I have done repairs on the inside, overall it's been the best truck I have ever owned.

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Great dealership!
Great dealership! I was a cash buyer with a trade in so was in and out in a little over an hour. I did feel like they couldb='ve given me a little more for my trade in considering I spend over $6K in maintenance on it, so that didn't sit right with me.
If owned Three Avalanche
It is a strong reliable truck and I would likae to have one for myself as a work truck and hauling heavy equipment like a man lift and compressor and still do some light duty work

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

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!

Great place to do business!
I've bought 3 vehicles from Gaffney Buick GMC. They are always professional and go the extra mile! I would highly recommend them for sales and service!
I bought this after going to the dealer just to look at
I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Another Satisfied Customer
I found the Service Manager to be very honest and straight forward. The team went the extra mile to ensure my truck was properly diagnosed and repaired to my expectations.
Overall I am very happy with my new Truck.
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?

Super People, Super Truck
Great experience from the moment I walk in untill the time I drove away with my new 2024 Sierra 3500. I was treated like family with respect and professionalism. Thank you for a smooth transaction. I will definitely be back to buy me next vehicle.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Excellent fast service service rep was easy to deal with, customer area was well kept with plenty of refreshments and comfortable seating. Coffee would be better if it was a keirig coffee machine
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.
