Awesome experience.
Awesome experience. Cody was professional and easy to deal with. I came from about 45 miles away and he knew what time I would arrive to look at it and take it for a test drive. Cody was honest and very straightforward with me.
Good afternoon everyone, yes, I’m a lady and I’m an owner
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

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.

My experience was outstanding with Mathis Motors and
My experience was outstanding with Mathis Motors and their sales team. The salesman Jacob was incredibly responsive and knowledgeable. He responded nearly immediately and was able to work the deal in the moment. We were able to set it all up in 30 minutes or less. The SUV is exactly as described and was cleaner than any used vehicle and most new vehicles I’ve ever bought. I appreciate all they did. I would and will give them my business again.
I love the truck. Dot trust that it won't brake do
The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

Josh Roseke was very accommodating, professional and accurate. He ensured the experience was painless and efficient. The dealership should be proud to employ an associate of his caliber.
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.

Jim in finance was great to work with also. Want to give a shout out to Max too. Over all, great experience. It had the WOW factor.
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 .

Excellent Service!!
I was in an accident and my car was totaled. I wanted to replace it with a new Nissan Rogue, it the car dealership that I got my last one at was no very anxious to help me find one since I hadn’t received the check from th insurance co. yet. Todd Eversgerd went out of his way to find a car, get the extras that we wanted installed on it, kept in contact with me re: when the car was delivered and the work was done, etc. He even went so far as to try to match the color of paint on the number of our license plate that had been scraped off during the accident! Eva’s very professional and went above and beyond in all aspects. When we got there, he was busy with someone else across the street at the VW dealership, so he had Matt help us wile he was over there. Matt also was excellent. He went over everything that Todd had written down including giving us the manuals, having us watch the videos, introducing us to the finance manager. Afterward,Matt took us out to the car went over everything about the car,and programmed our phones into the car. He then called Todd so Todd could make sure we didn’t have any other questions. I have never had anyone go to the lengths that stood went to make car buying so easy.Will definitely be back for our next car!
Would buy again!
Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

We were ready for a new vehicle and decided to go back to Jack Schmitt in Collinsville. Nick Karateew was my salesman before so we talked with him and he was able to make the deal for us on a new Ford Bronco! It’s beautiful and I can’t thank Nick enough for making this happen for us and being awesome to work with! I highly recommend him if you’re ready to buy a new vehicle! Thanks for all your help Nick!
My Work horse.
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.

Great team! I Was a walk-in. Friendly helpful staff - went into look at a Canyon. I found the truck online. Salesman TJ helped with locating the truck and brought it up to the showroom. Even washed it prior to me seeing it ! Great financial staff. Quick and easy!! I Will return in the future for more vehicles.

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.
