I was running a little behind and wanted to get my oil
I was running a little behind and wanted to get my oil changed prior to a Dr appointment. The service writer was a Rock Star. Got my truck serviced zippidy do da and off I went. Made my appointment with a few minutes to spare. I can’t thank him enough. I’ll do better about getting there earlier. Thank you again for making it a great experience.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Reasonable deals, not steal deals
What criteria do you have in shopping your next used vehicle? 1. You want to buy a used car that is believed to be absolutely trouble free (Equivalent to a certified grade). 2. You are ok to buy a car at a fair market price (You are not trying to find a steal deal or to negotiate a price). 3. You hate sales pitch. Then go to Carmax. This is my best advice based on my past car buying experiences with all sorts of car dealers. You can't go wrong with Carmax if the above three are your criteria. Carmax set an extremely high standard in their car reconditioning protocols. Carmax certification is as good as manufacturer's certifications. Meanwhile, you will be discouraged if you come to Carmax in hope to find a steal deal, because all of their cars are priced RIGHT, and they never give you a room to negotiate over the price. This means that they don't play games, and they don't let you play games, either. They are fair. You have to be fair, too. A good news is, they don't try to steal your money. So don't try to steal theirs. However, I have one serious advice: Get pre-approved by a local credit union before coming to Carmax. While Carmax too does offer financing, their repayment rule has a catch. Say your monthly payment was set to $100. If you put $500 at once, you expect that the extra $400 would automatically go to principal payment, right? Not with Carmax financing. Instead, the first $300 goes to the three upcoming monthly payments, and only the remaining $200 will go to principal payment. If you intend to pay off your auto loan quick, this repayment rule that they set up is a deal breaker. A good thing is, they will gladly let you use your credit union financing; they won't pressure you into choosing their financing service. Good luck, and never go back to liars that live in the rest of the world.
2022 GMC Sierra SLT 3.0 Duramax
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!

Most people don?t think of a dealership for routine maintenance but Koons Manassas as an excellent place to start. Prices are fair. Service is done on time and pricing is very transparent. Give these pros a try.

What a pleasant experience.
What a pleasant experience. My first time financing a vehicle. When going to initially look at the vehicle, I discovered a few issues. Obviously no used car is going to be perfect, nor was I expecting it to be. They told me to come back the next day and the issues would be fixed. I came back and they did in fact fix the car. They are willing to and have went above and beyond.

Excellent as expressed.
Excellent as expressed. Mr. Donovan was my advisor and he conducted himself in a manner that was extremely impressive. He was extremely knowledgeable and professional. He is a front man for this company and he represented himself very well. I appreciate this type service and will continue to return and will share my experience with colleagues.
Pleased that I made this purchase
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.

Good afternoon everyone, yes, I’m a lady and I’m an owner
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

I bought a new car. Everyone was helpful. It was a good experience. I recommend this dealer. I love my new car. Thank you very much.
I own a 2023 Sierra 1500 Elevation equipped with the 2.
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. :)

Hold your ground!
To be completely honest, this dealership is not bad only if you are buying a new car that is already on the lot. They sold me a car at MSRP with no other hidden fees. The reason why I took a star off is because they're very, very pushy. They will try to sell you on a different car so hard that they're trying to get rid of, and will keep pushing you to purchase warranties and all. They have a super hard time hearing no. If you keep standing your ground and don't get pressured into doing something you really don't want, this is actually a decent enough dealership to purchase a brand new car from only.

Great service and communication.
Great service and communication. Have a decent size inventory, you can definitely find the vehicle you’re looking for. I settled for a 2008 Ford F350 King Ranch. Beautiful frame and sound engine and transmission. Claudia was very helpful and very knowledgeable with financing. I left the dealership an hour later with a beautiful truck. Recommend!
My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
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.

They offer good Ford F150 4x4 trucks.
They offer good Ford F150 4x4 trucks. They offer full details on features. Unfortunately they only offer high mileage vehicles. 124k to 200K (too high). I am only interested in a Ford F150 2002-2003 4x4 with mileage not to exceed 60-80k max. I am a ready buyer with cash. ----- Robert LeBlanc
Great truck with some bad
It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

The staff at this dealership was extremely communicative and helpful. They honestly want to match customers to the right vehicle, and they go to great lengths to make sure their used cars work as well as possible. I certainly would recommend Mahwy Cars Inc. to all my friends.

Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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.
