What a pleasure to deal with salesman manager number one
What a pleasure to deal with salesman manager number one Would definitely buy another car from them in the future
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.

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Unbelievable shopping experience!
I had THE best experience at Carmax...the salespeople were non-pressuring, helpful and just amazing (especially Daniel!). They went out of their way to make every step comfortable and unpainful. I will most definitely go there when I need to buy my daughter a car and when I need to upgrade in a few years!
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

So far so good!
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 Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Lou was my salesperson and he was super communicative,
Lou was my salesperson and he was super communicative, explaining and re-explaining when he seemed to feel it was needed. No surprises along the way, I was able to test drive the van as much or as long as I wanted, have a mechanic come by to inspect it and they washed it and added a full tank of gas on pickup day. They had done some quality servicing to the vehicle as well before pickup day. Lou mentioned early on that he wasn't paid on a commission basis, which was a good detail for me to know. In the end, all the numbers were the same from the beginning to end, no "uh oh" moments and it was a super fast experience on pickup day - probably the fastest ever for me to get the keys and drive a new (to me) vehicle home. I will look to use them again if possible in the next year or so. Highly recommend.
This is your Truck
When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

This was the best experience I’ve ever had in all my
This was the best experience I’ve ever had in all my years of purchasing cars. They understood my situation, worked hard to accommodate my needs and most importantly they knew my urgency. They made it happen and did all the leg work so I did not have to. I walked out of there with my new used vehicle, insurance and registration. At the end of the day the hardest thing I did was wait while the made it happen. I got into my dream car for the family. May God continue to bless this business and I am worry free with a lifetime warranty on the engine. Thank you Sound Auto Wholesalers
a great Truck
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!

a place to go for bargains if you have patience
Alex excellent salesperson very patience and honest. The dealership is another story, if your looking for a reasonable price this is the dealership for you, they get cars from Auction so no idea about the history of the car, they get checked when you already signed for the As- is purchase, don't go there on a weekend, if you have patience, wants a bargain, (non negotiable deals)time, and good mechanic this is a place to go, got lucky with Alex very accommodating and great salesman
One very awesome vehicle.

The salesman was great. No pressure and willing to negotiate. The finance guy was even better. Overall great experience buying a car.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Easily one of the smoothest & most trustworthy
Easily one of the smoothest & most trustworthy transactions I’ve ever experienced with a car purchase! Will never go anywhere else moving forward. Dejon N. was kind, knowledgeable, and very patient as I asked a ton of questions. Financing staff equally as lovely & incredibly helpful. Highly recommend this location! Thank you!
So far have loved my 2020 2500 HD 4x4 diesel
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.
