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. :)

Very helpful salesman and finance manager. Whole deal was closed with a test drive in one and a half hours. I will check here first when buying a vehicle again.

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 !

Great as usual Kevin B. is the best master mechanic that people travel from other states to see. Will the service adviser is equally as good at servicing and comunication.

My salesperson Joseph was excellent to work with—friendly, knowledgeable, and never pushy. He made the whole car buying process much easier and answered all of my questions.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

I had a very positive experience with Nick and his team at McGee Toyota in Epping. Nick was helpful, informative gave me the information that I needed. pricing was fair and reasonable, and I appreciated the explanations I was given. He showed me around the car, And even though I knew the vehicle I wanted when I got there he was Very congenial and honest about all of it. I appreciate that.

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!

There are dealerships that sells cars, and then there are dealerships that sell an experience. From the initial sales contact, to service, parts, back office/finance and the genius sections, this is a very well run dealership. The sales process is no-pressure, respectful but with knowledgeable professionals who will answer questions as best they can. The service section is equally well organized and the few times that I have needed any repairs, it has been nothing but highly satisfactory. If you care about building an arrangement beyond just buying a car to having a trusted relationship to maintain your car, this is a place worthy of your full attention.

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

Had a good experience there, the salesmen were all great answered all of our questions, we'll go back if we should need another vehicle.

Justin was a great guy to meet, and made our choice on finding our car easy ...thanks Justin !

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.

Excellent salesman Scott. Dealership impeccable. Everyone professional and courteous. Explained every detail of buying process. Finance staff Kendra extremely professional and explained every process of leading my 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.

Shop is clean and mechanics are knowledgeable. Service advisors are also very helpful. Experience overall is great. I will continue to rely on them for my service.

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.

Amazing experience. I'd recommend anyone looking for a car to try CarMax first... There's zero pressure, tons of beautiful vehicles, and just an all around great place. Will definitely be buying from here in the future. They're willing to work with you if you don't have the best credit, and most importantly, they're just honest and transparent. Two very important things when spending tens of thousands of dollars. Put it this way, it was great enough experience for me to come online and leave reviews all over!

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.

The single element that changed my opinion from never going back to the dealership after I bought my truck to now am willing to always go back for EVERYTHING (including driving the 1 hr each way) for something even as small as an oil change, is the service department. Chris, the service manager, and his team make the experience a pleasant experience. This is a result of their ability to identify and fix issues with the vehicle but with the personality that they also have. They engage with me, are always friendly but not patronizing, and add to the clarity that is often missing with customer - service interactions.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

When waiting repairs. It?s a very comfortable place to wait. 2 different waiting area?s both with tv?s. Coffee, water and soda always available!

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

First time buyer from Alliance met with great service very happy with my vehicle the team is very helpful I will recommend Alliance

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Fantastic experience, these folks make it easy to buy a vehicle. We will definitely be back.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I was looking for a used Jeep and after looking around, this dealership really took care of their used cars. The jeep that I purchased from here was well maintained and clean! There were some small parts missing from the vehicle and when I purchased the vehicle, the dealer ordered the missing parts for me for no extra cost. Overall experience was great and would highly recommend.

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Although I didn't walk off the lot with a car, I will say I very much enjoyed my experience here. The gentleman I dealt with was very nice and courteous. Wasn't at all pushy and tried to work with me the best he could. They even had someone drive the car 20 minutes out to see my technician. They really went out of there way to make things work. Unfortunately, we were not able to work things out, but If ever need to shop for a car again, they will be on the top of my list to check out there inventory.
