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

I can’t recommend this dealership enough. Trivan and the rest of his team were a pleasure to deal with from start to finish. I was treated with honesty and respect and therefore they earned my business now and in the future. Thank you for a wonderful buying experience.

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.

The purchase was totally done online. the dealership helped me every step of the way. MS Farrah Barber the finance manager made the purchase easy. Mr. Tavin Gordon the dealer even took a full video of the vehicle in real time for me. I was very impressed he is awesome. I then drove the vehicle from the dealership to San Diego with no problem.

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 !

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!

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!

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.

Awesome experience. Everyone was kind and informative. The car buying experience was completely stress free.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

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

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 new car manager did not beat around the bush. He gave me clean fax finance payments interest rates. It was no xxxxxxxx when you went to see this dealership is all about business and friendship.

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

The team at Carmax Gaithersburg was amazing! So appreciate their patience, attentiveness, and professionalism! Great job!

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

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.

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.

Great salesman very easy to talk to plus worked hard on getting me a great deal

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Equinox was in for repair from accident. Repairs were expertly done. The color was matched totally. Had to make numerous calls for updates since I never received a call until SUV was ready

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

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.

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.

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 car is a fabulous car for family and traveling. It is roomy, has capacity for kids and sports gear, and is safe. I have been rear ended twice in a Yukon and there was minimal damage to the Yukon and extensive damage to the other vehicles.

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!

had an awesome experience. Everyone was very helpful and I was able to find a great car within my budget. I will definitely be letting anyone who needs a car know about this dealership.

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.

Good deals but didn't get to purchase a car today. Have to get a cosigner. Plenty of choices payments okay. Problems with using my old vechile as a trade in. Interested in selling my jeep and using the funds for the purchase of a new car.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

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!

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.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

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.
