Used GMC Sierra 2500 trucks for sale near Milton, GA under $1,000,000

Recently purchased a truck with Eddie Martinez and had a good experience. Eddie was professional and honest throughout, and he was able to tell me a lot of the vehicle I wanted to purchase. Go see Eddie for your car needs!

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.

Andres was great and very helpful. Although we didn't purchase we would definitely work with him again. We highly recommend him. He's honest and not pushy.

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!

Very nice and knowledgeable one of the best experience I’ve ever had at a dealership, hands-down

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.

Nolan Knox from Carl Black, Roswell, was so easy to work with in purchasing our new Sierra 1500 denali ultimate. Nolan was so professional and knowledgeable as he answered all our questions. I highly recommend Nolan Knox. Thank you for making this whole purchasing event less stressful. Charles & Deb

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

About two weeks ago, I found a Lexus RC 350 at CarGurus and I stopped by for some window shopping and ran into Lou, who was helping another customer at the time. Even though the showroom was busy, He took the time to greet me and reassured me that someone would be with me shortly. That simple gesture really stood out and made me feel valued, even before I made a decision. After doing my research, I decided to return to ALM Marietta, and I'm so glad I did! I had the pleasure of working with Lou again, and I also had the chance to meet some fantastic folks in both the management and finance team.

Thank you, Aliana for all your help I really appreciate everything you have done for me.

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.

Manny Platero is my dude to go for services on my whole fleet of cameros.

Hands down this was the most pleasant and stress free car buying experience EVER! My senior sales consultant was Shenita Monroe at Carmax Norcross , who was an excellent salesperson to buy my 2015 Subaru Outback car from . Highly professional , courteous and detailed , are the words that come to mind to describe her exemplorary customer service style . We initially enquired about the vehicle online and discovered it was at the Kennesaw Carmax location . She immediately requested a transfer so that within 24 hours we could conveniently test drive and finally purchase the car. She is the real deal and we can't recommend her enough . Please make this woman a sales manager !! 5 STARS...

Great personality, very understanding and entertaining sales person, will definitely be back. Rod Williams made this car search the best experience ever. He is a awesome sales manager.

Working with Ben Clark has been a game-changer. His professionalism, attention to detail, and ability to deliver solutions tailored to our needs made the buying process seamless. Ben not only helped us achieve our goals but also ensured we felt supported every step of the way. I would highly recommend him to anyone looking for a trustworthy and results-oriented sales professional.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Excelente servicio el que nos ofreció Kenmanuel gracias a Dios y a él logramos la compra del vehículo, excelente vendedor nuevamente gracias Kenmanuel por su gestión

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Kenmanuel hizo un excelente trabajo, mi familia está feliz y yo contento por la amabilidad con que kenmanuel nos ayudo

I came in for oul change and my Rear riverside tire leaking down. it took over 3 hours to complete work. I was grateful that the tire was replaced with a new one., but they did not put valve stem cover back on nor did they clean the white sealant material from around tire and wheel. I think they could have been more customer focused

I was looking to upgrade my truck and met Nolan Knox who helped me look for the right truck. He was patient as I tried to make the best decision for me. He responded to all my questions even when he was off. I would recommend Nolan to help anyone with car or truck buying from Carl Black GMC of Roswell.

Benjamin was great. Very attentive to the details. Got me a new truck, even though I thought I was going to get one before coming in to the dealership.

Very pleased with service I received. It honest, helpful and answered my question and concerns. Greg was able to satisfy what I needed and I would recommend purchasing a car from this dealership.

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.
