Was contacted by Zach from Waterbury dealership.
Was contacted by Zach from Waterbury dealership. Right off the bat I felt like he understood my needs and wanted to work a fair deal for the sale of my truck. We got it done and myself into new Colorado. Staff was very helpful and patient. I would recommend this dealership team to anyone. Thanks!!
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. :)

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!

Great truck to own.
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.

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.
2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Todd helped us buy our new car.
Todd helped us buy our new car. After seeing other cars and dealerships coming to Highline was refreshing. He was so pleasant and very prompt during the testing of vehicles. Cars were pulled up right away back to back with zero down time. I love this. Considering they had a busy day with many customers in the office we still received great care. We closed on a 2022 Honda Accord and are in love. The manager closed the deal and experienced was everything as he too was great

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.

Working with Ray to close the deal was amazing. He is very familiar with the vehicles and options available to the customers. He knows the material and how to get his customers to their end goal. Thank you Ray for helping us drive away with our new Truck!!!!!
Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

As a first time buyer and financing I was apprehensive about right step to take in a field so vast. I wanted honesty, guidance, clarity and a vehicle that will meet my needs. At Car Corner I found Rick and he kindly walked me through every step explaining clearly all paperwork and car information and because my time constraints he did it all in a day and out the door I went with my new to me beautiful car, completely inform, happy and with at the bottom line is most important! Peace of mind.

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.

Nice showroom and a beautiful selection of cars. I looked at a 2015 Ford Mustang convertible and worked with Danny, who was friendly, professional, and laid-back. There was no sales pressure and I was able to get a good price on the automobile. Service provided a detailed review of their inspection and upgrades. They instantly addressed a small mechanical issue that I had with the car, and it was detailed and looked great on delivery. Highly recommended this dealership.
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.

Wonderful Vehicle.
I purchased to replace a 2017 Tahoe that I loved. Love this vehicle even more. Magnetic ride control, additional safety features the Tahoe did not have are great. Heated steering wheel a great feature. Heated AND cooled seats, will never be without again. Additional power of the Denali 6.2L vs. the 5.3L engine in the Tahoe is impressive. Bose sound system is outstanding.

Gengras always delivers.
Professionalism and efficiency in there delivery is not easy to find. Richard is always so attentive and make me feel quite at ease. Went in for an unusual sound coming from under the car and was told my car would not be ready the same day because they did not have the part, and due to the holidays. I was offered a loaner. The next morning I received a call that my car was ready. The part came in early, service was done and I had my car back in 24 hours. 😊
