Used 2023 GMC Sierra 1500 trucks for sale near Fulton, MD

Just purchased m 7th truck from general manager Dennis Koulatsos. I've been buying trucks from Dennis since I first met him in 1991. He is the consumate professional, and I've referred all of my family members and dozens of friends to him, and he's taken very good care of all of them. Dennis is fiercely loyal, a man of his word, and he always goes the extra mile.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I have not been to this location in many years. I was so pleased with the level of service. The gentleman that assisted me was very helpful and explained the process of the repairs for my car. He also helped me with a rental car. I was not feeling well and exhausted but he made the process very easy and he was patient with my many questions.

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!

In October 2020 I purchased my 2020 Ford Explorer ST at Koons Sterling Ford and have loved every minute of driving it. I've had it in for regular maintenance and recalls at the dealership but just recently on September 26, 2025, I had my best experience when I brought my Explorer in for a new battery. I had the pleasure of having Bradley Cadenas as my service rep and was very impressed with his professionalism and his outstanding product knowledge regarding my Ford Explorer. I wasn't aware of the FordPass reward points I had accumulated, and Bradley was very helpful in helping me manage these and applying them towards the cost of the new battery and related service work. I felt like I got the "red carpet" treatment and look forward to working with Bradley in the future--he is a credit to the dealership and particularly to the service department. Keep up the good work!

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.

Michael Henry is an excellent salesman! He listened and worked hard to get me the car I was looking for.... of course I did my research to know what I was looking for .... and more importantly, he found the car at the price I was looking for! 5 stars to Michael! Make sure he’s the person you use to find you the right car for the right price! He was very patient, professional and mindful! I also appreciate the length Carmax agreed to go to to ensure I was satisfied with the Vehicle to fix needed repairs. I give them 3.5-4 stars for that. I did not like the loaner car that Service put me... it was not good to borer line okay.

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.

My salesman Bradley went above and beyond for me at first he didn’t have the truck I wanted in my price range but a few weeks later he called me back and had exactly what I asked him for with only a few miles on it and a diesel on top of that I would defiantly buy from him again

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

Had great a customer service with Jonathan, he answered all of my questions, and also explained everything that my vehicle was getting done. Absolutely recommend working with him.

Overall a great experience, not a lot of the usual dealership back and forth hassle, I was in and out in under 3 hours as they were pretty straightforward on pricing. The salesperson was new but very pleasant. Overall a great job by the team at Ourisman!

Was researching and looking for a used car for my daughter for a month. Seen the perfect car pop up on Heritage Honda website. Went in on a Saturday and was greeted by Eyo. Eyo enthusiastically was able to show us the car, arrange the test drive, and handle everything from start to finish. Was thoroughly impressed with how everything was handled from the car showing through the financing. Would definitely recommend Eyo and Heritage Honda for your new and used car buying needs.

Matt is really helpful and friendly. Even though we didn’t make the purchase since I was looking for to get a better trade in price, but overall it’s very good! I have been to carmax twice and both of them are all very good facilities and very professional working process, definitely recommend Carmax!

Very Good Experience, everything was quick and Detailed, staff was patient and answered all of our questions and concerns, got the deal done no sweat.

They got me where I needed to be on payments got me in and out. I was running tight on time. It was a pleasure working with them.

Excellent interaction with Will Coral in sales as I was looking to purchase a Tesla Model X. Will was honest, genuine, a good communicator and made best efforts to make it a smooth and fair transaction. I plan to consider this dealership for future purchases.

Very good dealership. They were professional, honest, fair, and helpful… exactly what you’d expect from a quality, reputable dealership

I’ve been talking with Athina Batis, the sales manager. She has been super helpful and on top of everything to help get me going, I’m from MA and drove down to buy a truck and needed plates and registration help. She went above and beyond to make sure I had everything I needed. Can’t thank her enough!! Highly recommend her for anyone looking to purchase a vehicle from the dealership!

Very helpful Abu and Tonino went the extra mile I am very happy with their services

Great overall experience. Casey was good to work with in sales. He was knowledgeable and no pressure. Prices were better than nearby dealerships for similar used models. Slight hiccup with the business office team during pickup. They couldn’t find my paperwork from a couple days before. It caused a few minutes delay but the team was professional and helpful throughout. Hopefully titling and registration goes quickly.

A very welcoming dealership ... sales rep was most helpful. Sheehy was eager to work through a couple of issues that slowed the sales process a bit. Had a happy outcome.
