Used GMC Sierra 2500 Denali for sale near Alpharetta, GA

Recently purchased a SUV for daughter Baker and Keanen delivered the vehicle and completed all of the paperwork. The delivery was smooth and their dedication to us and the sales was commendable. I do highly recommend.

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.

From start to finish Kenmanuel made the process hassle free and easy. Amazing customer service.

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.

Ayy, real talk — I pulled up thinkin’ this was gon’ be the usual runaround at the dealership. But then I linked with Manny Platero, and everything switched up. Bro came correct, handled his business, and treated me like a VIP from the jump. Wasn’t no gimmicks, no fake “lemme see what I can do” type vibe. Just solid service, real communication, and straight-up respect. He told me what the car needed, kept it 100 the whole time, and didn’t try to finesse me on no extra charges. That’s the type of professionalism you don’t see enough of — especially in this game. Time is money, and Manny respected both. That’s Atlanta energy — hustle smart, keep it real, and treat folks right. So if you in the city or even just passin’ through, and your ride need love — go ask for Manny Platero. He ain’t just a service advisor, he a real one. Salute from the 404.

Greco es un excelente tipo para vender y explica todo muy bien estoy muy contenta con la compra q pudimos Realizar el d�a de hoy

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.

Reggie was the best! Thank you for everything. Would defend recommend that you ask for him to assist with your purchase.

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!

This was the easiest car buying experience I have had. They took me to the car I was interested in. Keys were there, we drove it right away. The price was competitive, the financing was lightning quick. They washed it while I was signing and I was out of there in under an hour. They even drove me to turn in my rental car so I could just drive my new car home and surprise the family. First class business.

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

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

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.

Recently purchased a vehicle with Alex. Definitely recommend him to everyone. He is professional and would find the dream car for you. Will find him again for future purchase.

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.

John Miegel is a true replica of what America used to be. Very friendly and a great place to do business. They are more honest than most places I have done business with in recent years Simply put, I love and respect this establishment' customer service and their business ethics. 1st Class to DUSTIN, BLAKE, JEREMY & JOSE !!!

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!

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.

Jesus Flores was a great and caring individual that helped me and my son with our purchase and made it so easy.

My experience was excellent with Ted. The videos from the technician ere very informative. My son-in-law had a previous car worked on here and also purchased a new one from Ellis GMC.

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 is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Damien Brown was super helpful on the phone and even more so in person. This dealership has a huge inventory and he was very knowledgeable about all of the different cars available. There were no pushy sales tactics, and I never felt pressured. I would absolutely seek him out again if I were in the market to buy another vehicle.

Kenmanuel was extraordinary salesman he give to us more the 100% customer service. We back home happy with our new vehicle

Great Service- Kenmanuel is best. This is the 2nd time ive worked with him in the last year & I couldnt be any happier!

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Salesperson courteous friendly, very knowledgeable and very helpful. Financing options explored to reach our budget goals. .

James really does put the customer first, really nice to see he's really there with my best interest in mind.

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Benjamin did a great job finding the car for me. He was very direct and helpful.
