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!

Favorite car I have owned, to date!

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Highly Recommend
I have recently been looking for a Jeep Wrangler and came across Midwest Autoplex during our search. They had a great inventory to select from. Jeff was awesome to deal with! We had a few requests and he was very accommodating. The whole process of purchasing our vehicle went very smooth. I highly recommend Jeff and Midwest Autoplex.
My dad bought the Sierra brand new in 2004 and I recently
My dad bought the Sierra brand new in 2004 and I recently got it as a hand me down 2nd truck, and all I can say is it's perfect for what I need. Most reliable truck ever and I can get up to 16 in town and 22 on the highway. The 5.3 liter Vortec LM7 is probably the best engine ever made. The transmission is very responsive and the truck is surprisingly quick. And the 4 wheel drive works. My S10 never did that. Would definitely recommend. My only complaint is the ride is quite stiff with the twin leaf spring tow suspension, but it's supposed to be because it's toe suspension.

Best salesforce of any dealership that I have ever worked with. They met all my needs and I love my MKZ
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

My new vehicle
The team really took the time to help me figure out exactly which vehicle was meant for me! They all worked very hard to find my best deal for me, I am loving my choice!!!
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

Everyone has been very conscientious and courteous checking back with me to determine what I want and if I was aware of the age of the vehicle. They also informed me that their service department wanted to work on some issues with the car and that they would let me know what they did and what work they believe still needs to be completed.
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Newest & Biggest SUV I've ever owned
The styling looks great outside & everything functions as it should. It has loads of options, heated & cooled seats & steering wheel, very cold air, big comfy 7 seats. While not a luxury-looking plush interior, it is very nice. A couple pieces of plastic molding inside are loose, a back panel I tried to take off & the visor mirror on drivers side. I've owned this for 6 months & adore it! Very roomy.

Everyone was so nice to talk with and made us feel like we were a very important customer. The facility was clean and had adequate seating for us to rest.
Stylish and comfortable.
Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.
