Used GMC trucks for sale near Crofton, MD

Took BMW i5 in for routine maintenance/inspection. Checked in effifiently, waited in wait area with magazines and screen. Estimated time was 3 hours, which was accurate. I was contacted by text during inspection with photos showing progress. Checked out efficiently.

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.

Big shoutout to Chris for being such a huge help! He walked me through programming my new HondaLink and made it super simple. Excellent service and very friendly.

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.

Shane was very helpful in getting us into a new vehicle ; I would highly recommend their service

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!

Brian Perry and Jeff Bejna provided excellent service. They were very honest, accommodating, and I felt at ease during the whole buying process. I highly recommend Heritage MileOne!

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.

Just purchased m 7th truck from general manager Dennis Koulatsos. I've been buying trucks from Dennis since I first met him in 1991. He is the consumate professional, and I've referred all of my family members and dozens of friends to him, and he's taken very good care of all of them. Dennis is fiercely loyal, a man of his word, and he always goes the extra mile.

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.

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.

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

Nate & Sam, I want to take this opportunity to extend my sincere thank you for selling me my new N Line. I have been leasing and buying cars for 35 years and this purchase experience was by far the most pleasurable. Both of you responded immediately to questions, negotiations and everything needed to make the purchase happen in a timely manner. Upon arriving at the dealership it took less than 45 minutes to take delivery without any surprises from finance. Again, thank you for making this happen and worth the 6-hour roundtrip from NJ. I will recommend AL Packer Ford to family & friends. Nate & Sam, I want to take this opportunity to extend my sincere thank you for selling me my new N Line.

Mr Nicholson was a true joy. He was as on top of everything I asked for and he met all of my expectations I would recommend him and the dealership to my friends and relatives. .

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 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.

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!

I am buying a used car after 8 years, and this was great experience. No haggle is what I care. I was not forced to buy GAP insurance or anything else. The only complaint is, the lady taking down payment at the cashier was hesitant to tell me the details of the transactions before making a payment and showing attitude, but everyone else was great. I highly recommend this carmax.

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!

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 purchased a Nissan rouge, told the dealer what I want in my rouge and they found it for me. I also purchased a camero. Professional staff. I will always get my cars from Carmax in Whitemarsh

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.

Got two cars from here and everyone was so nice and helpful. Will definitely be back. They even delivered the second vehicle for free.

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

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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!!!!

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.

Javone assisted us in buying a new Toyota RAV4 and did an excellent job every step of the way

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.

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.

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 !

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