Used GMC Sierra 3500 trucks for sale near Garrett Park, MD

MY experience with Trust Auto was seamless from start to finish. Our sales agent, Kate was professional and delightfully pleasant. There was never a hint of pressure or surprises with hidden fees. Therefore, I highly recommend this dealership.

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

Had such an amazing experience! Was a bit nervous to purchase a new vehicle especially in this market but the staff & service were outstanding & comforting. They educated me on every step & were so helpful with any questions/concerns I had. I've been car shopping for some time now but I'm beyond thankful I was able to find DNT. Would recommend to anyone in the market looking for a trustworthy dealership in the DMV. Finally got the Lexus I've been wanting & with the beautiful inventory they have, I will definitely be back when it's time to upgrade!

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

I recently purchased a 2025 Ranger Raptor from Ourisman Ford in Manassas, and I can’t say enough great things about my experience with Nirbhay! From start to finish, he was absolutely phenomenal—professional, knowledgeable, and genuinely focused on making sure I got exactly what I wanted. Nirbhay made the entire buying process smooth and stress-free. He kept me informed at every step, answered all of my questions with patience and clarity, and went above and beyond to ensure I was getting the best possible deal. His transparency and honesty were a breath of fresh air, and I never once felt pressured. The Ranger Raptor is an incredible truck, and Nirbhay made the experience of getting behind the wheel of it even more exciting. His follow-through and attention to detail were top-notch, and even after the sale, he checked in to make sure everything was perfect. If you’re considering a new Ford—especially something as awesome as the 2025 Ranger Raptor—do yourself a favor and ask for Nirbhay. He’s one of the best sales professionals I’ve ever worked with. Thank you, Nirbhay!

This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Josh was great and made the whole buying process run smoothly. He was very knowledgeable and even set me up with the my Chevy app which is very convenient.

THANK YOU SKIP AFTER I TEST DROVE MY SHELBY I WAS OUT OF THE FINANCE OFFICE WITHIN 20MIN THIS DEALERSHIP HAS THERE ACT TOGETHER I WOULD HIRE SKIP TO WORK FOR ME

We received outstanding customer service from Luis Arredondo when buying a 2023 Chevy Bolt, which I am very content with and enjoy driving. The price was reasonable. Luis was always responsive to our inquiries and focused on our needs. I also really appreciate their Sunday sales hours. Service was great in reprinting the key.

Love these guys! They made buying car very easy after being denied in my state every where I reached out to them and was they help us almost that day get approved! Love these guys I bought a 2016 Mercedes-Benz GL-Class GL 450 4MATIC AWD 4dr SUV came how they described no problem and they delivered quickly all within a matter of days. Buy a car from these guys they were pretty transparent and kept it 💯 with us. I will recommend all my people's here...!!!!! P.s even took the car to a known place to uncharge on work and they said they couldn't find anything wrong. Of course I purchased a warranty which they also gave me a great deal on. I appreciate you guys 🙌🏽👌👏

The truck met all my expectations and more so far. the engine is powerful and the ride is smooth. the interior is great and so are the things this truck has.

Great service and friendly people. Donna an is the best. The SUV is running great.

Schedule my Service appointment Friday for Monday 7am. Received my second text on Sunday. Mr.Rodriguez BPH Service assisted me thank you. My car came back clean.

I purchased a Ford Maverick on 30 December. Nelson Hernandez was the salesman assisting me. Nelson worked a solid deal for me after finding the right model that met my requirements

Jay was great. They helped me every step of the way. I appreciate everything they did for me

This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

My family has purchased two cars from Malloy in the past two months. Alex the GM has clearly instilled a collaborative team culture, as everyone we worked with on both transactions went above and beyond. From hunting down the interior of the bronco sport we loved from another dealer, to ensuring we got the value we wanted for the Jeep we traded in, they were a pleasure to work with. Car buying is never an easy process, but Malloy makes it as painless as possible.
