An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

I have loved and owned Chevy and GMC midsized trucks
I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Great place and service department. Always a pleasure to be there. Friendly staff. No place I'd rather go.
Perfect for us!
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

Awesome Salesman and Great Price
I live in the Indianapolis area and found the SUV my family was needing. I talked to Shawn and told him I wanted an honest description of the vehicle before I drove 5 hours to purchase it. When we got their it was exactly what he described. I would definitely buy from Shawn again!

Excellent Car buying experience.
I had a very pleasant experience buying pre-owned Buick Enclave at Midwest Autoplex. They had exactly what I needed and the best deal I could find in town. The car runs great. Very low pressure and they gave me plenty of time to test drive and inspect the car before buying. Car was very clean and Jeff was great to work with. I would definitely recommend this place.
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.

Great experience. Jimmy was great and answered all my questions. love my new Yukon XL 2025. I would definitely recommend Jimmy and this dealership to my friends and family.
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

This was my second vehicle purchase with Cardinal GMC,
This was my second vehicle purchase with Cardinal GMC, and I have to say, the experience this time around was a huge step up, all thanks to Matt Columbo. My first purchase didn?t go as smoothly, but I met Matt when I came back for service, and he immediately stood out. He took the time to notice an issue I was having and actually helped make it right, which left a lasting impression. So when it was time to buy again, I didn?t think twice, I went straight to Matt. He made the entire process easy and stress-free. He was knowledgeable, patient, and genuinely cared about getting me into the right vehicle. I love my new Buick Envision and couldn?t be happier with how everything turned out. If you?re heading to Cardinal, ask for Matt. He really goes the extra mile.
Great Pick-up
Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

The salesman I dealt with, Rob Fulmer is one of the best.
The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!
Nicest vehicle we've owned
I'm 6-4 so I'm looking for a comfortable vehicle that's easy to get in-and-out of plus is high quality. I don't buy new cars and in our 40 years of marriage it's the nicest used car we've purchased.

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Great people,easy buying process
Great vehicles,they made buying so easy and smooth,great staff very friendly very polite East to find location,in a great neighborhood ,I would highly recommend to all my family and friends
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.
