Used GMC Sierra 1500 SLT for sale near Ashton-Sandy Spring, MD

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.

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 had an excellent experience at Easterns Automotive of Sterling. Eddy went above and beyond to make the process fast, pleasant, and thorough, ensuring everything was handled smoothly from start to finish. Tony, the manager, made sure the final steps of receiving the vehicle were seamless and took care of my requests right away. The team as a whole made this a very positive car-buying experience, and I would definitely recommend them.

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.

The technician was very helpful and courteous. He provided an overview of the health of my vehicle, which was informative and helpful for me to plan my next maintenance visit.

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

Our sales person was excellent Constantinos tsounis got it in the car I want it and in and out the door at at a very reasonable amount of time I would definitely refer friends and family to them

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 !

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.

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

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.

Jason at Fitzgerald Buick is always so helpful to us. They are always upfront with us and work hard to help us get the best deal. We will continue to go back anytime we need another vehicle and will definitely refer friends and family to them.

I’m very satisfied with my experience in dealing with Purmotive. They are a very professional organization and very upfront and knowledgeable of the vehicles they are selling. I highly recommend them.

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

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.

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!

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.

JR and the team was superb! The buying experience with Sport was non stressful. They truly know how a customer is to be treated with knowledge and understanding!

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Best pricing in the DC market, we searched many vehicles and platinum auto sales has the best price for the car we were looking for by far so happy we came and bought here! free carfax was provided to us and great customer support

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.

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

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

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!

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!

Appreciate the service. The best service around. I will continue to take my truck there. I love how the show you videos of the service on your vehicle.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Everything was exactly as described! Very friendly and helpful staff. I flew in from out of state and was very pleased with my purchase!

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.

Kasim was and still is great to work with! So grateful for all his help! We love our new “used” car and felt right at home as soon as we got there. The whole team worked hard to achieve all our goals and went over the top to get us all done is a timely manner. Couldn’t have asked for a better experience! Hopefully we won’t need a new car soon but if we do we will be back to see Kasim! Thank you Kasim!!

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?

Levon was my salesperson. He was phenomenal!!!! He made the buying process easy. I truly enjoyed working with him. You will truly enjoy your buying experience!!!!

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

GREAT JOB Keep up the Work Salesperson was very Helpful and Quickly Response Take Care!

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

We have always had a positive experience at Upper Marlboro Ford. The automotive service we received for a recall on our Mustangs met our expectations and we will continue taking our vehicles there to be serviced. I would also like to note whenever we visit the main showroom we are greeted immediately with a warm, friendly, and very accommodating staff!

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
