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.

Shawn DeMint is an awesome salesman. He listened to what we needed and worked hard to find us the best vehicle. He made the entire experience stress free. Thank you Shawn!

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

Just had an oil change done, but they got me in right away and was done quickly.

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

great service, very professional, good check points for condition of vehicle

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

There are a lot of places that buy/sell/work on cars. Ben, Bill and the folks at Sleepy Hollow are the sort of people that make the difference. The service department handled my repair and insurance claim seemlessly, and they gave me a very fair price for my vehicle- knowing I had my eye on purchasing another elsewhere. It’s worth going out of your way to do business here- perks of a big dealer with a family atmosphere. I’ll be taking my vehicle here in the future.

Vehicle is very nice and has all the bells and whistles. I bought it to pull a 26 ft Airstream and it does the job but not great, could use more power for towing. It is difficult now to find a vehicle to pull a large trailer. I didn't want a pickup because I haul a large dog that takes up the entire back seat. I wish they still made the 3 quarter ton Yukon with the larger motor like I used to have. You could haul anything with it. The Yukon XL with the 6.2 motor just barely does the job.

Overall We were pleased with the purchase of the vehicle and decided to buy it after leasing for 3 years.

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

I visited this dealership to review a car seen on Cars.com. Although I live 4 hours from the dealership, I will probably end up buying this or another car from them. They are that good. Their prices are all "no haggle." so the price you see is the one you will pay. No guessing how much lower they will go. They won't go any lower. This makes the transaction much cleaner and faster. The staff goes out of their way to be helpful, even if you are just looking, as I was. The dealership pays their sales staff a salary. Because their is no incentive for them to make the sale, their is no pressure to buy a car. It's a great shopping experience.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Was in for normal service this time. Had purchased the vehicle there several years ago and always service it there.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

Drove my truck into the express lane and was addressed immediately. Waited in the customer lounge for what seemed like a very short time. Excellent service!!

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

I am so vey happy to have purchased my vehicle through Brenengens. My sales person was Steve "Kubby" Kussman, he was wonderful to work with. (VERY FRIENDLY) was not pushy in any way. I had a couple issues after my purchase (which were not serious) but Kubby and Pat McKenna (car manager) took care of them right away. They were so good about it. I was very happy with that. So many other times I had purchased a vehicle elsewhere I had issues with getting help with the vehicle I had purchased, which is the most frustrating thing! I am 3 1/2 hours away from Brenengens , but the next time I am looking for another vehicle, I am going there 1st. I am also letting others know how good they are there. Cindy Schwartz

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

Everyone was very friendly and easy to work with. Service department fix serviced my vehicle fast

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!

A Lengthy service was complimented with a courtesy car to go on with my day.

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.

Mark was an amazing salesman. He was extremely well with product knowledge and no pressure. I would buy again. Thanks Mark

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Great customer service and repair! Chris Young is an abosolute professional! Wonderful service repair department! Took the time to fit us in the schedule on a Saturday afternoon to repair our vehicle so we could travel out of town the next day for work. Thank you!

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?
