Used GMC cars for sale near Walker Mill, MD under $40,000

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!

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Repairs were made in a very timely manner, extremely happy with my service adviser Drew, and the technician that made the repairs. Everyone at Criswell was friendly, and the facility was very clean.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Excellent experience! They've earned my business in the future. The car buying process was seamless. They made me feel very comfortable. I'm grateful for their promptness and consideration!

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 !

Was a very efficient process, everyone seemed nice and I felt I didn't have much to worry about. Had a concern with vehicle's battery - they replaced it and allowed me to get it inspected at their Honda dealership, just to make sure everything was in place. 2 months in so far and no car troubles - I'd recommend this dealership to anyone in the area.

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.

Great service my repairs were done correctly & all necessary repairs due were written on report for future service. I loved the video done by my service tech, which showed exactly what was needed to be repaired

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Shaky experience. Very slow response and lack of communication from my service rep, but the service manager ensured that it was a pleasant experience. All of the employees were pleasant and professional.

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!

My wife and I drove up to Koons from Ashland to look at a used car. We ended up not feeling it was a good fit, but Omar asked us to check out the terrains. We were hesitant at first but took one for a drive and ended up loving it. After a few days of thinking and some research we purchased one. Omar was such a great help, not pushy at all and very understanding that I like to do a lot of research. He was willing to work with us on price and we walked away with a fantastic deal on a brand new car. I highly recommend Omar at Koons if you're looking for a laid-back purchasing experience with no pressure. A week later Omar gave me a call to make sure everything was going well! Thanks Omar!

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.

This was the best car purchase experience ever! Quick and smooth. No haggling straight forward and honest. Mr. Bentley went above and beyond. Great experience.

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

They were very nice to work with I had no problems every thing was great an car was delivered at the right time the wife was happy, beautiful car thank you.

I purchased to replace a 2017 Tahoe that I loved. Love this vehicle even more. Magnetic ride control, additional safety features the Tahoe did not have are great. Heated steering wheel a great feature. Heated AND cooled seats, will never be without again. Additional power of the Denali 6.2L vs. the 5.3L engine in the Tahoe is impressive. Bose sound system is outstanding.

My problem was with the AI contact point at King. Stupid me, I thought Olivia King was a person, and I emailed "her" several times with requests. Before I went in, cars.com asked me to review "her" and the email included a photo of a woman, again making me think I was dealing with a human. When I went in, I asked to speak with her, and was finally told she didn't exist. But was I embarrassed and did I feel stupid! It was very deceptive. And this is not how you want a customer to feel when you're selling something. You need to make it clear up front that the email contact is an AI contact, and any salesperson will be there to help at appointment time. Other than that, it was a good experience. King even allowed the car to be driven 33 miles to my mechanic for an inspection. That's extraordinary. The car was in good shape, and we closed after returning from the inspection.

Has everything you'll ever need, You will enjoy it for years on end. It rides high so you don't have to worry about not seeing vehicles coming.

Hands down, the best dealership in the United States! From the moment I walked through the doors, I knew I was in a place that truly values its customers. The level of professionalism, warmth, and genuine care displayed by the staff is unmatched. This isn't just a dealership, it's an experience. What sets this team apart is its extraordinary customer service. Every interaction feels personal, as if you're reconnecting with old friends rather than meeting someone for the first time. Several team members made me feel like they'd known me for years, remembering small details and going out of their way to ensure I felt comfortable and valued. The staff is not only knowledgeable and efficient, but also incredibly kind and approachable. Whether you're buying your first car or returning for service, they treat you with the same level of respect and enthusiasm. It's clear that this team is passionate about what they do—and it shows in every handshake, every smile, and every follow-up call. To say they have an excellent team would be an understatement. They’ve built a culture of excellence that radiates through every department. If you're looking for a dealership that combines top-tier service, heartfelt hospitality, and a commitment to excellence, look no further. This is the gold standard.

This is a really nice vehicle for being used. It exceeds our expectations for comfort and performance. We enjoy driving it both in town and out in the country.

Good experience. No issues with the service. Obviously the cost for repairs could be cheaper but the service is good. At least I'm able to know what is wrong with my vehicle and make a decision on what I want done.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Buying a vehicle at Sport Chevrolet is a very pleasant experience. The sales team are professional, courteous, and friendly. I would recommend this dealership.

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'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.

They were very helpful and very professional the dealership was very clean and the dealership inventory was updated I would buy my car from the dealership if I could

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.

Found a vehicle on Truecar that I liked & went to dealership to check it out. Car was super clean, detailed & took for a test drive. Had a car to possibly trade & they gave me a fair price. A no hassle, stress free transaction from the minute we walked into the dealership till the minute we drove away in a newer SUV. Glen Carter was very professional, knowledgeable and easy going. Talked with Finance, Bianca, and signed some papers & was out the door. Highly recommend this dealer ship!!

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.

I live in PA and did online buying and delivery. Guillermo was responsive and helpful. The gents who delivered the vehicle were very nice. Thank you to all who was involved.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Arlington Motors of Woodbridge used cars experience was great. Hassle free, and great customer service. The team worked well together. Would recommend buying a car from here.

This Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Had a fantastic experience at the dealership — friendly, no-pressure, and delivered exactly what I wanted. Highly recommend!

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

Honestly, one of the nicest, friendliest place around. Very helpful when buying a vehicle from here. I’ve been to many other places looking for cars and was so stressed out until coming here, they made things easy and the process very smooth. Highly recommend.

I love it so much lots of space .. every thing clean no dents or scratches every thing is perfect all everything fully loaded the best
