Used GMC Sierra 1500 SLT for sale near Olney, MD

Went here randomly one morning and had the pleasure of working with Lorenzo as my sales rep. Wonderful customer service, personable and not pushy! Walked my wife and I through the process & we even played cards while we waited for everything. 10/10 would recommend. Made the stressful car buying experience an absolute breeze.

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.

I am glad I purchased my 2015 GMC Yukon SLT from Len Stoler Chyrsler Dodge Jeep! I originally wanted a Chevy Tahoe, but just as I was able to sign her away, there she was, my dream truck! The family fell in love with her just like I did when I first saw her. Our salesman, Blair Ruckman was fantastic and a genuine professional throughout the entire buying experience. The communication between us and his team, ensured my needs were met, without any issues. I definitely will be back for all my service needs and to purchase my family's next vehicle. Thank you Blair and the rest of the Len Stoler team!

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. :)

Nelson is the most wonderful salesman’s great work great dealership everyone so nice this is our 5th car with them !!

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

My service advisor, Michael, was the best! I had an inquiry about my car and he took the time to check everything and even test drive it. I then had to get a new battery and was lucky enough to reach Michael again and he got me in and out before I could get settled in the waiting room! He was very patient and personable. Great service! I highly recommend him and this dealership!

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.

What a pleasant experience. My first time financing a vehicle. When going to initially look at the vehicle, I discovered a few issues. Obviously no used car is going to be perfect, nor was I expecting it to be. They told me to come back the next day and the issues would be fixed. I came back and they did in fact fix the car. They are willing to and have went above and beyond.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Shelly is amazing. I recommend her to everyone I know looking to buy a car! She was very fast friendly and very knowledgeable. I can’t thank her enough for all of her work. I love my car!

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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.

Wayne is great! Ask for him. I love this dealership, Easy and fast. Will recommend this place to my friends and family.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Atmosphere was pleasant and all of the personnel was kind and professional. Especially my salesman Earl Jones He made the whole process so easy. The other salesmen were very kind also. Koons is the way to go when buying a vehicle.

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!

Stupid accident brought me to see Mike in the body shop. Second time the garage door gouged the hatch. Mike took the car right away fixed it and cleaned it up better than when I dropped it off. Thanks Mike, great job.

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?

Awesome dealership. Billy Wilson was a knowledgeable sales rep. I got a decent deal on a near perfect 2022 id4 pro S. Bravo!

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

Responded very quickly and was always there when I needed to talk or have a question, gave me good deal

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.

I had a wonderful experience with Caleb Polen, both trading in my vehicle and purchasing the new one. I would highly recommend Leesburg Buick GMC and Caleb.

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.

Javon, was excellent, he listened to everything that I wanted and was able to identify what was important to me and was able place me in a vehicle that met all my needs.

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!

Maria Pikney at the Ourisman Chevy on Security Blvd site, she is knowledge about the purchase process, through on the Chevy brands Equinox and Blaze and I purchased my new 2026 Equinox Sat Oct 11th, 2025

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 staff at this dealership was extremely communicative and helpful. They honestly want to match customers to the right vehicle, and they go to great lengths to make sure their used cars work as well as possible. I certainly would recommend Mahwy Cars Inc. to all my friends.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Quick and thorough. I was told exactly what was being done and how much it would cost. I was informed of upcoming things to watch for.

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.

I recently purchased a 2025 Kia Sportage Prestige, and I couldn't be more pleased with the exceptional service I received from Donny. His customer service skills were outsanding-he actively listened, was incredibly knowledgeable about the vehicle, and kept me well-informed throughout the entire process. This is the third car I've purchased from this location, and I was intially unsure if the experience would match the high standards set by my former salesman who is no longer there. Donny reassured me that I was in good hands, but he was wrong-I was in great hands. I had considered other brands and wasn't certain I would stay with Kia, but Donny's patience, professionalism, and thorough answers to my (many) questions made all the difference. He was truly phenomenal, and the overall sales experience was marvelous thanks to him. Donny's outstanding service is what ultimately sealed the deal. Highly recommend asking for him if you're in the market for a vehicle! I am writing to follow up on my previous message regarding my concerns with the Finance Department. I am pleased to share that since then, the team at King Kia of Laurel has gone above and beyond to address my concerns and turn my experience into a positive one. I would especially like to recognize Larry, Carlos Mendez, and Matt Aglio for their extraordinary efforts. Their professionalism, responsiveness, and genuine commitment to customer satisfaction were truly impressive. Thanks to their support, I now feel confident and valued as a customer. I appreciate the time and care taken to ensure my concerns were resolved and that my experience ended on such a high note.

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!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

I’ve been with SMH Auto Sales for years, and I wouldn’t go anywhere else.” I bought my Cadillac ATS 6 years ago from them and about 5 years later I loved it so much that when it was time to upgrade, I came right back and got my Cadillac CT6 through them too. Waited & got what I wanted, picked out! 🤗🤗The entire team at SMH Auto Sales is awesome!! they’ve helped me with everything over the years. From financing and service to body work and customization (they even helped me get my CT6 completely blacked out 🔥), they always go above and beyond. The owners are super nice, easy to talk to, and genuinely care about making sure you’re happy. If you’re looking for a dealership that stays with you long after the sale , this is it. Whether you need advice, service, or just want honest help from people who know their stuff, SMH Auto Sales is where you want to go!!

It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive
