Used GMC Sierra 1500 SLT for sale near Poolesville, MD

This was hands down the best car-buying experience I’ve had in all my years. I’ve purchased vehicles from Mercedes, BMW, Acura, Jeep — you name it — and none of them came close to the level of professionalism, honesty, and hospitality I received at Koons GMC in Vienna, VA. The deal they offered was so incredible that I traveled all the way from New Jersey by Amtrak to Virginia. I’ll admit, I was skeptical at first because many dealerships pull bait-and-switch tactics. But not here. Saleam (Sales), Sait (Sales Manager), and Isabella (Finance) all confirmed the deal ahead of time and honored exactly what was promised. When I arrived just after opening at 9 AM, Sales was still in a meeting, but I was greeted respectfully right at the door. Saleam was paged, and the process began immediately. She welcomed me warmly, gave me a brief tour of the dealership—including the much-needed coffee lounge—and handled all the paperwork, insurance details, and my Costco rebate flawlessly. Sales Manager Sait was exceptional. He thanked me personally for my business — something I’ve never experienced from a sales manager at any dealership in the past. He even told me to call him anytime if I had questions or concerns. That level of care is rare. My experience was elevated even further by Finance Manager Isabella. Her energy was absolutely to the moon. She helped close the best deal I could find anywhere in the NY/NJ/CT tri-state area and the entire DMV region. She offered an unbeatable protection package at a discount, covering dents and mileage, and explained everything clearly and thoroughly. She also respected my time, wrapping up the paperwork quickly since she knew I had a four-hour trip back home. I cannot recommend this dealership enough. If you’re reading this review, do yourself a favor and consider Koons GMC in Vienna. I would happily send any of my friends, family, or colleagues here. They’ve earned a lifelong customer.

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!

Excellent and prompt service. They did a great job and were very informative throughout. Highly recommend!

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 !

I do not have a review. your finance person was interested in giving us a higher interest rate. may be they make more money as such

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.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Ernest helped us with purchasing our 2022 Tahoe. Ernest is patient with our questions and did everything to help us feel confident in our choice. I would recommend Fitzgerald to anyone! This was a great experience and I look forward to coming back for our next vehicle! Thank you Ernest and Team!

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.

Best car buying experience by far. Will refer everyone to this dealership moving forward. Thanks!

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?

Dealership was easy to find. Employees were very nice and great to deal with. Salesman seemed to have a lot of experience in the car selling/buying business. Some dealerships will try and rip you off, I had no such experience here at South Street Auto Sales. Owner of the dealership stepped in on my purchase to make sure all was going well. I bought a brand new 2013 Mitsubishi Evo with under 200 miles on it. Walked out saving a lot of money. I recommend this dealership to anyone. Nice antique cars to look at when waiting around. I did have to wait a decent amount of time because the finance manager was busy with other customers. No problem for me with the deal I walked away with.

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

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!!!!

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.

Jimmy at Carmart. was absolutely terrific. Out of the dozens of times I have bought a car from anyone this was the most smoothest ever one that I felt no unease about. Jimmy took care of a problem after the sale with no hassles even picked up and delivered my wife while his crew worked on the car. By far the best dealership I have ever worked with. If you’re looking for an honest dealership that you don’t feel will cheat you this is the one.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Great service in an emergency We were leaving town for a vacation and noticed that the car needed an oil change before we left Our service rep came through for us

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

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

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

They beat my credit union apr, happy with the car and warranty i got easy transaction

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.

Another great service visit at Safford Jeep! I owned a Mercedes for many years and was accustomed to superior service...and had high expectations. Safford Jeep service department always exceeds my expectations with efficient, expert service, and friendly, courteous treatment. Most of my satisfaction comes from the efforts of my service advisor Alex Alvarado. It's nice to be greeted by someone who knows you, and your vehicles. I'm certain he'll be the manager of a service department at some point. Keep up the good work Safford Jeep!

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.

Darius provided us with great customer service. We addressed a few minor cosmetic issues with the vehicle and he immediately took care of them. I will highly recommend Eastern Automotive Group to my friends and relatives looking to purchase a vehicle.

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.

I have a 2010 Escape snd have gotten all my service here. Yesterday Daniel was very helpful.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Nice guy and was honest about everything 💪🏼💪🏼💪🏼 I was impressed with the car and price

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.

Sales persons were very informative and provided quality service. Sales manager took time to confirm eligibility for all possible rebate offers. Financing took time to answer all questions and reached out for confirmation on questions from customer.

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

Great and trustworthy team! This is my second vehicle purchased from them, and I couldn’t be happier. I’ve checked other options, but their prices are much better for the same mileage. Highly recommend these guys!”

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.

Excellent customer service.! Bilingual employees a plus. Sales assisted quickly explained everything. Happy with the purchase thank you.

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

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.
