Used GMC trucks for sale near Mount Aetna, MD

From the first email to the final handshake, Ashlee Varner was there to support my new vehicle needs! The Team of sales made my experience!

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. :)

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.

Friendly and helpful salesman. Made sure I understood as much as possible about the car and followed up with me the next day.

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

As always, Shively provided great and timely service at a reasonable price, and the staff were very helpful and attentive to our needs

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!

My experience was hassle free. The price was fair and the sales person did everthing to make this the easiest car purchase I have ever experienced. I didn't have to wait hours at the dealership and the car was exactly what I was looking for.

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.

Jared brought a very pleasant and professional experience to Honda purchase. He is very knowledgeable and very nice to work with. I would definitely buy another car from Jared

We traded our 2010 Subaru Forester for a 2016 Subaru Outback. The entire process took about two hours and was hassle free. This included test driving the Outback (while they we doing the appraisal on the Forester), transferring plates, taking care of payment, etc. They make car buying a breeze!

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

Shelly is amazing. I recommend her to everyone I know looking to buy a car! She was very fast friendly and very knowledgeable. I can’t thank her enough for all of her work. I love my car!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Great dealership with very helpful friendly staff. I would recommend Renn Kirby Mitsubishi for all your vehicle needs.

I love this truck. It’s quiet and comfortable. The V6 has enough power for me. The options I got are convenient and make for a luxury car experience.

Sales process was very transparent and timely. The car was delivered to my home as promised.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

Brian Chanin did a great job working with me on my purchase. He was upfront with me on the whole process, because my budget was a big concern. We knew the car we wanted, but we were tight on funds. At no point did I feel pressured to make a decision. He just explained where we were during the discussion and make sure both my wife and I understood. Once the deal was in place, he checked in on us with the finance department, and even helped migrate the items from our trade in to our new car. Great experience.

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

I was in and out no problems and was right in on my appointment time I usually have to have a late appointment because of my work and that was real good

Am I the only one that has had the instrument panel completely fail? Mine did YEARS ago. So why is my reliability rating 5? The computer still works, I know how fast I'm going, the Miles remaining on the fuel economy is accurate, and it runs. Everyday. Replaced one hub and bearing, water pump, starter, ignition. A/C doesn't work, but I've got windows (which work if you know exactly where to push the button.) Oh, and the Engine light is always on, because the throttle body really needs a thorough cleaning or replacing. Motor and transmission have been crazy reliable for 20 years on truck bought new October '0 3. Nothing a few hundred dollars wouldn't fix. Though there are several of those, they don't keep me from getting from A to B.

They did the job on time with no problems. Great Job. Kept up the GREAT work with your team and I will see you in the future for services.

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.

Good. Arrived and was waited on in a timely manner. Attendant was courteous and attentive. I have options closer to home but chose this dealership for service.

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?

Loved the compact car updates and there's need to be a navigation menu when they are chr cars updated

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

Shelly got me in a car that checked all of my boxes and I’m still a happy customer. The buying process was quick and the staff was very professional.

I’ve been with SMH Auto Sales for years, and I wouldn’t go anywhere else.” I bought my Cadillac ATS 6 years ago from them and about 5 years later I loved it so much that when it was time to upgrade, I came right back and got my Cadillac CT6 through them too. Waited & got what I wanted, picked out! 🤗🤗The entire team at SMH Auto Sales is awesome!! they’ve helped me with everything over the years. From financing and service to body work and customization (they even helped me get my CT6 completely blacked out 🔥), they always go above and beyond. The owners are super nice, easy to talk to, and genuinely care about making sure you’re happy. If you’re looking for a dealership that stays with you long after the sale , this is it. Whether you need advice, service, or just want honest help from people who know their stuff, SMH Auto Sales is where you want to go!!

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.

Very pleasant. Enjoyed working with Louis Lee. The whole team worked well together and I am happy with the outcome.

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.

Service was excellent. Called the dealership inquiring about a 2010 honda civic. The sales representative, Shane Heimberger, put me on hold to verify the car was still available and physically held the keys so it wouldn't be sold while we were on the way to view it. Car was exactly as described, and parked on the side awaiting for me to test drive. Shane, showed us the inspection information and basically told us everything that was wrong with the car. Purchased the car, and they delivered it the next day to my home over an hour away. Very pleased with the service, would definitely recommend them to a friend.

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

I had a wonderful experience buying my new Kia at Darcars Kia of Frederick. My salesperson was Parrish Francis and he was so helpful and walked me through every step! I will definitely go back again for my next car purchase.

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck
