Used GMC Sierra 1500 trucks for sale near Hampstead, MD under $899,990

Courtney and Wes were great to work with. They both made our purchase easy and painless! We will definitely be back at Thornton for all service and maintenance on our vehicle.

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!

First time buying at Koons Joe was my salesman. It was a very seamless sale I would recommend seeing him for your next purchase

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!

Courtney in service is great, keeps in touch constantly letting me know the status of the repairs. Most of the time able to get a service appointment quickly.

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.

Purchased a 2017 Acadia Denali, Everyone I worked with did everything they could to accommodate my request. There was absolutely no pressure to by the automobile. Great place to do business.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Our salesman was Scott. Extremely knowledgeable and helpful. Entire experience (bought a 2026 GMC Arcadia) at the dealership was excellent. We moved quickly through the process. Will go back for future vehicles.

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

The teamwork of the sales team was outstanding. Can’t say enough about how seamless the process was.

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.

Outstanding service all around ! Immediate availability and quick completion of service! Satisfaction guaranteed! Thank you!

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. ??????????????????????????????????????????? ?????????????

Ron Kessler is absolutely amazing! He genuinely cares about his customers and always does what’s best for them. I never have any worries when I know Ron is fixing my car. All staff at Thornton are always super kind and welcoming! Hunter was especially kind and helpful!

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.

Sharee at Ourisman Chevy on security blvd. In Baltimore serviced my vehicle. I believe she goes above and beyond, she lessons and has patience and that means a lot.

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!

I had a great experience with all the staff I dealt with. All of my questions were answered and I was not pushed ti do anything I didn’t want. They were able to get me into a payment range I was looking for. I love the car I purchased. Best car buying experience I have ever had.

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.

I would like to thank Corey, I had a small issue with my suv and he jumped right in to solve the problem and it was taken care of in no time. He is the best!!!!

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Kevin Bacon is reliable and trustworthy. I depend on his expertise for my 2006 Buick Lucerne to operate safely, reliably and efficiently.

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!

Brian was great to work with no pressure to buy, Told him what i wanted and he was great at making it happen, He wants me to call if any problems so that we are happy, Paper work was quick and painless, Love my new Yukon Denali,

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

I Purchased a 2015 Tacoma TRD PRO on line. I'm 3 1/2 hours away so everything was phone and email. Couldn't have been an easier process. I was sent a video walk around of the truck and the manager pointed out every little rock chip or imperfection. From Wes the Manager to Brian in Finance to Ryan in Sales...Top Notch! I'm like a lot of people that don't like dealing with a car dealer...I've had bad experiences in the past. This was the smoothest, easiest transaction I've ever had at a dealership. The truck was priced fairly and when the shipper delivered it, the condition was exactly as I was told, No Surprises! I would buy from these guys again in a heartbeat. It's nice to deal with responsive people that shoot straight and do what they tell you they will do! Great Job Thornton Automotive.

I found the exact vehicle I’d been searching for online. It was not in my home state which made me nervous but I contacted them any way. Brady made my buying experience effortless, smooth & easy. Best of all, no pressure. Everything was done for me. From contacting my credit union, giving me a good price on my trade in & registration in my home state. I was able to leave with my new car that day. I didn’t think that was possible but the folks at Len Stoler made it happen! I would make the trip to buy from them again.

Bought a 2022 Santa Fe from Alec Deese. My Wife and I were looing for one and Alec sent us a message that one had come in to the dealership and we went to look at it. Took a ride in it and car rode very nice and was very clean. We bought it. Alex was very helpfull in getting the car. We would recommend Jack Giambalvo Hyundai and Alec to anyone looking for a good car. Thank you.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

My husband and I stopped by Awesome Autos Saturday evening before they closed. My credit had taken a little hit from covid. I had a couple vehicles in mind. They happened to have what I was looking for on the lot. Kia Soul, with a manual transmission. We were greeted by Ryan and had a wonderful experience. The staff along with Ryan helped obtain a payment below what we were anticipating. Go see Ryan and staff at Awesome Autos

Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

My husband and I were so pleased with our recent purchase of a new truck from Koons in Clarksville. Our sales person Jack was absolutely amazing. From pricing to just plain great customer service we were so pleased. No pressure just a great deal. Thanks Jack. Will definitely share our experience with others.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Recently I took my 2011 terrain back for repairs for the 2nd time. After facing a bill of $492.00 Mr. Bacon understood my problem and told me "don't worry , the parts are on the way and your window will be fixed. He later told me that they want me to pay $100.00. I told him my 1st visit was within my warranty and I shouldn't even have a bill. Later he came back and told me "you're good". I thanked him for his services. I will call Mr. Bacon for future services.

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 salesmen and the people there we're excellent, but unfortunately the car it was not in good enough shape that I could purchase it. It wouldn't pass inspection

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.
