Used GMC trucks for sale near Crofton, MD

No fuss no muss. I did my research before hand and it took a grand total of 2.5 hours and I was driving away in a Gladiator.

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.

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.

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.

Excellent customer service! Was in and out in no time. Will continue to bring my vehicle to Koons

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!

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

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.

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.

Thank you to Hamza in finance and Dave in service. Both were very knowledgeable and helpful and we were able to get what we needed done in a timely manner.

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

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.

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

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

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.

Outstanding dealership on all counts. Service, sales customer accommodations, noting but good stuff. They have taken care of 4 of my cars and sold me 2. Did a brief detour to another brand and came back to them because the service experience here was so superior. They go out of their way to take care of you.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

This dealership was to me way down in Pasadena. Truthfully thought about turning around on Wednesday. Decided to keep going. Arrived and was met by Robert, a totally up front individual. He pulled out the vehicle gave me keys and said try it out, I will talk to you when you return. The professionalism he possessed was exceptional. We had a 45 minute discussion and I bought the vehicle. I explained that I had no way to get back to the business, from just below Towson to pick up the vehicle. Robert didn't hesitate and said not to worry we will work something out. They delivered my vehicle on Friday and gave me gas $. This was totally the exception and a worthwhile 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.

Spent alot of time with me trying to find the vehicle i am interested in.

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

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.

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!!

Anyone can sell a car, but it’s how you handle the challenges that truly sets someone apart. Mike and Mohammed went above and beyond selling me my new SUV. They stayed true to their word from start to finish and delivered on every promise with complete integrity and honesty throughout the entire process. I can’t recommend them highly enough. If you’re in the market for your next vehicle, these are the guys to see!

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

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.

Fantastic buying experience. In and out quickly with a fair price. I highly recommend purchasing your vehicle here.

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. :)

Went in to purchase a car and drove out with a 2026 CT4 V Blackwing (manual).

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.

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 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!

Sheehy of Laurel great dealership David Jacobs great service rep and the reason I come here
