Used GMC Sierra 3500 Denali for sale near Derwood, MD

I recently purchased a 2025 Corvette Z06 at this dealership and I had a great experience! Jack, who was my salesman, helped me and went above and beyond throughout the whole process and made my buying experience great. He was so helpful, made sure I knew everything about my car and was always there to answer all of my questions. He is one of the nicest people I have ever met, and he even personally drove the car I purchased all the way to my home in Virginia. Jack is AMAZING and I would come back just for him. Hamza was also extremely kind and helpful and very intelligent. He made sure I was informed about all finance aspects of the car and he made sure I made the right choice when purchasing my maintenance plan. He has always been so helpful and even to this day if I have any questions, he is always there to help me. Please promote these two employees because they are absolutely amazing and the stars of that dealership!

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Dealt with Rodrigo on my purchase mainly over the phone. He made everything go smoothly and didn’t play any games when I arrived. His communication was great and I would highly recommend him.

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.

This place is top notch. I bought a vehicle back in 2023. I called them to have them send me a picture of a truck that I wanted from them that had already sold. They informed me that I could have them do all the modifications at there shop. So I shopped the country and I bought a truck in Tennessee and had it shipped to Krietz Customs in Maryland. They fit me in, and I had it shipped to my house in Massachusetts. I was so impressed with how easy of a process this was. This company is top notch! My wife and I happen to be in Maryland for a wedding about a year later with my truck. I wanted to have new custom upper control arms done on it so I swung by and met all of the friendly people I had only met on the phone a year prior. I was so impressed that they were able to fit me in with the limited time we have. Thank you guys for being a company I can trust and count on. I wanted to Mention one of the sales team people Marlin, he was top notch. He showed me around the lot and we had a great conversation. God Bless all of you And thank you again for a great experience Adam/ Crystal Wood

If I were to use one word, " Impressive"! From selection, to customer service to Dylan! Dylan you are the absute greatest. You've made this experience seamless for us and I'm now suoer eccited to call myself a a Krietz Family member! Thank you so much for answering every question, on time...all the time!

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.

Bought my truck online. 2024 GMC Denali My salesman Gavin did a wonderful job super easy experience and truck looked even better then the pictures.

Just wanted to give a shoutout to henry n lisa n kreitz auto team. its my 2 nd vehicle i bought there in they never disappoint such a great experience.

Kash and the Sales team were awesome.!! Great prices ,easy process!!! Would definitely return for my next GM vehicle.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

I’m very happy with dnt-seller.I bought a 2020 rx350 the seller are very helpful and friendly. I will give the sellers a 5 star.Thanks moe.

Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

Mr. Shores listened and was abje to make it happen. I got my truck. Pete from the Aftermarket Dept. Made sure to go the extra mile so I can have my truck taken care. Excellent Customer Service. Thank you. Linda, Southern MD Linda 1500 Dodge Ram

I had a wonderful experience with Caleb Polen, both trading in my vehicle and purchasing the new one. I would highly recommend Leesburg Buick GMC and Caleb.

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.

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

I recently had my car serviced at Koons, and I want to highlight the excellent customer service provided by Robert Ryan. From start to finish, he kept me well-informed about my vehicle’s status, ensuring a smooth and stress-free experience. He provided timely updates on the progress of the repairs, explaining everything in a clear and professional manner. Whether it was diagnosing the issue, ordering parts, or giving me an estimated completion time, I never had to wonder what was happening with my car. His responsiveness to my questions and proactive communication truly made a difference. Beyond just providing updates, Robert was courteous, knowledgeable, and showed genuine concern for my satisfaction. It's rare to find such dedicated customer service, and I truly appreciate his effort in making the process transparent and hassle-free. I highly recommend Robert/Koons based on this experience, and I would definitely return for future service, knowing that I will be kept in the loop every step of the way. Thank you, Robert, for your outstanding service! ⭐⭐⭐⭐⭐

Super easy and fast transaction at imperial auto! My Girlfriend & I inquired about a Mercedes C63s AMG ! & Salim helped us with the Sale & got us the best rate possible! especially with these rough times we are going through with the rates being Ridiculous. our buying process only took 30-45 min MAX just like he said before we said YES to him. I highly recommend Salim & imperial auto check them out!

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.
