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 dealership experience.
Great dealership experience. Sales guy was very clear on pricing over Email and delivery process is extremely smooth as well. They provided fair tradein value for the vehicle. I will definitely recommend
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Outstanding Experience
Because this is such a wonderful vehicle, I purchased it at the end of the lease. Dan and Russ were incredible in making this a seamless transition. My vehicle was inspected, rims repaired, appropriate services rendered, thoroughly cleaned plus received an excellent offer for new tires. I have been trading for many many years with Dan Ramsdell and his team. This experience is once again reason to make the John Thornton family of dealerships my only source for our family vehicles. Highly recommend this team now, just as I did three years ago. Thank you!!! The lease of my new 2020 Chevy Blazer was flawless. This was the third vehicle that I've leased from Dan Ramsdell. We have worked out the details on this transaction (all three) via email. I took limo from Atlanta airport to John Thornton Chevrolet, they opened at 8am just for me. All documents were ready, I only had to sign them and was our in thirty minutes. This gorgeous Black Blazer AWD 3LT has been detailed, filled up with gas, my all weather floor mats put in place and temporary license applied for tag with requested black license plate frame. Derek Strickland saw to it that everything was orchestrated perfectly and my transaction was seamless and most enjoyable. I will definitely trade with these professionals once again and highly recommend others to visit John Thornton Chevrolet!!
Awsome
Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Extremely satisfied with my new car!
Extremely satisfied with my new car! Awesome experience with the entire purchase process. A+ to the salesman Mark for getting me the best deal. His patience and knowledge is to be commended. Thank you!
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.

Very helpful. Transparent pricing. Handled all paperwork and transport. Just the car we wanted at a great price
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 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.

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Excellent service
I was stressed because the car just shutdown at the red light, however, when I arrived at Pugmire dealership, the Lincoln service had notified them and "Barry" made the loaner tranistion smooth and assured me they would service my car Monday morning. Just being in town for a 10 day vacation, Pugmire and Lincoln Service helped to make my trip to Atlanta **Fabulous**with absolutely no regrets.Thanks Barry, Pugmier and Lincoln!!

Superman disguised as customer service advisor!
Was in town for my sons lacrosse tournament when our 2022 Equinox broke down. Limped it over to your dealership at 7:30 in the morning to hopefully get an idea what was wrong. I was not expecting any miracles especially without a appointment as a matter of fact I figured I would be stuck there a few days until they could get to it. GET THIS...Bryon Steinke(employee of the month) greeted me and listened to my problem even though he was backed up with customers as far as the eye could see. Took my car and said lets see what we can do. Had me out of there in less than an hour, WAIT...it gets better. He called me Monday morning to see if me and my family got home safely!!!! Who is this guy and where did you find him because there is nobody in customer service like him any more!!! Can't say "thank you" enough times for what he did for us, that is a great employee you have there and you are a great dealership!!
Most expensive auto I've ever owned.
Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

The service department is outstanding. They let us bring our pitbull in and sales personnel and service personnel love him. He loves walking around and visiting everyone.
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.

I just want to say that I had a very professional
I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down. Aaron...
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????
