Excellent buying experience!!
Excellent experience all the way around! A special thanks to Brett Harness for following up with me and making my vehicle purchase happen even though I inquired about a different vehicle a month before. I was extremely pleased with everyone involved in the entire transaction at this dealership. Highly recommended!!

I bought my 2020 Enclave new and have been totally pleased. It rides better gets better mpg smoother more quiet and a much better ‘road car’ than the compatible Mercedes and BMW company cars I’ve driven. The tranny seems to be in the best gear more often without the annoying hard downshifts. The only option I wish Buick would offer is a third seat delete… I very seldom use the 3rd seats. It would be nice if they were removable like my Rendezvous seats which offered much more cargo space without them. The excellent road manners and smooth quiet ride shortens my 450 mile trip to my daughter’s house…. And I made it there without stopping for gas! 16.3 gal to go 451 miles… on a 310hp engine. I always liked my Chevy Caprices… but this Enclave is actually better and no problems just like the Caprices.

THE BEST HYUNDAI DEALERS AROUND.
Thank you Andy for taking the time with me in purchasing my new Sonata. Showing and telling me about the new features of my Sonata. Thank you also for your assistance in helping me with my accident. I will definitely recommend you to anyone who needs a new car. Also thank you Ryan for your assistance in handling my finances. You are both amazing and Awesome. Michael Simpson.
Who said that a family needed a Suburban vacation
The exterior is sporty. The placement of the vehicle's features are well placed. All three rows give even tall people room, such that they do not feel confined. With four adults and a toddler, we were able to have enough space to carry all planned luggage and snacks for a 2400 mile round trip journey. With all this space, I can still get this vehicle inside the garage.

Traded my Rogue for a 2020 Buick Enclave and I am loving
Traded my Rogue for a 2020 Buick Enclave and I am loving it. It is comfortable which matters to me since I am older. I don't know if it would be that popular with a younger generation but for long trips I think even they would like it, especially if you have kids. It is great when traveling with our dogs and we could sleep comfortably in it if we decide to stop at a camp site. I do wish it had some standard things on it that my Rogue did. The seats are more comfortable than the Rogue. I wish the cruise control automatically adjusted the speed. I wish it had a Lane departure warning.

This review is for Jimmy, one of the sales associates here. I spoke with him about my options for trading my vehicle. He was very knowledgeable and helpful. Now that I know my options, I’m looking forward to working with him in the future!

My only complaint is that I cannot seem to close the door mirrors. Small complaint and not really a flaw but cosmetic. The car is amazing. It has plenty of room and acceleration. It is comfortable and luxurious too.

CarMax made the purchase of my vehicle run smoothly, without having to go to the Division of Motor Vehicles. They addressed my concerns promptly and, when new keys had to be made, offered a "loaner" vehicle until the problem was fixed. I recommend CarMas to everyone!
Dependable If Maintained
it is 2023 and it has 146,000 miles on it with no major repairs. I change oil ever 5K miles and do all scheduled maintenance. My wife loves it. She can carry lots of her stuff and it easily converts to handle passengers.

Went to look at a Rav 4.
Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.
Excellent Vehicle
I have owned this car for almost 2 yrs & it’s been very reliable & comfortable especially on long trips I would definitely buy again very happy with it.

I had the absolute best experience at AutoNation in St.
I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.
Great Vehicle
I have owned this vehicle for over a year and a half no problems very happy with it. Very good for long trips. Would buy again.

a dynamic, professional and friendly team. Visit Autonava to drive your car. Thank you highly recommended
Yes! I will eventually drive this gem!
I can't write too much about this vehicle. The shop has had it longer than me. There seems to be an "out of balance" kind of shake when the vehicle reaches about 25 MPH. I have no doubt that the service team will find and correct the problem. I purchased this vehicle based on the fact that my mother had a Somerset and lent it to me for a week. That car was very comfortable and I knew this Enclave would live up to those standards. The SUV comfort was off the charts compared to that Somerset. For the short time I have driven it, I was pleased. I hope the shop finds the problem soon. I miss the comfort

I have had no real problems, except maybe the cheap tires they put on when its new. 23,000 miles and down to the wear bar. Sometime the info screen is frustrating to get the right pressure to find songs with the music channel I have. I do worry about the short warranty. 3 yrs 20,000 miles which is over. I cant believe that I overlooked that. I worked at GM for 8 yrs so I got the discount and that was why I bought it. If I had to do over I would by one of those Asian cars with 10 yr 100,000 mile warranty. Though I have had no problems so far. I only put about 7500 miles a yr on my car. I have 23500 now.

Honestly I am 65 years old bought 40 vehicles in my life it was one of the most pleasurable experiences I'm 65 but 40 vehicles in my life and this was a very straightforward enjoyment in my life to buy a vehicle from them I've ever had with buying a vehicle the people were great honest I don't believe they would rip anybody off and I would highly recommend they have nice vehicles all price ranges I go there first
Bought it used in May 2022.
Bought it used in May 2022. It's a 2016 Buick Enclave awd Tucson Edition (displayed as leather). It's a nice car, was around $28,000 from carmax with 70k miles. It's first problem occurred in June 2025 when the ac stopped working, it got fixed. Only major problem was at 105k miles when the transmission had trouble. Reason why was because the dealer said it had the 4,500 lb tow package, but it was missing a crucial part needed to tow. Transmission was fixed, and car still runs fine to this day at 108k miles. 3.6L V6 288 horsepower.

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.

This car met all our needs. Love the color and the interior design. Alloy wheels are very nice. Engine performance is excellent. Ride is very smooth and quiet.

Everyone was nice and the place was extremely busy.
Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.
Luxury that delivers
I absolutely love this car. While being priced on the high end, this is a luxury car that delivers. With 310 horsepower, 9 cylinder transmission, and luxurious interior appointments, this car delivers power and can definitely leave you feeling spoiled. The only issues that I have seen are really minor. The fuel door, when opened, can actually dent the body of the vehicle. The interior shade on the moonroof is a manual latch, not mechanical. It simply seems a little cheap compared to the rest of the car. My model is an Avenir model, but it does not have the advanced cruise control or the self parking modes. It did not have a significant price drop for not having these options and I am not sure why an Avenir model did not have all of the options available. I had to buy it during the chip shortage and took what was available. Altogether, this is the nicest car I have ever owned and I am very pleased!

For a car made in China, with their reputation for
For a car made in China, with their reputation for putting out shoddy products and looking at their buildings and roads that's falling apart as we speak, I was totally surprised at the quality built into this car, not knowing at the time of purchase that it was made over there, which would have made me pass on buying it. But we are talking GM here, that built the plant in Shanghai, who took every part over there just to use their labor only to assemble it, and they did an excellent job. I figure that GM pays them better than all other jobs in that country and they don' t want to lose that job, so they do the best that they can when putting it together. We are at 105,000 miles now, and did all the oil changes and did go through the hundred thousand mile checkup and all fluids changed, and it has yet to have anything to go wrong with it except for changing out the 5 year gel filled very expensive battery *at 5 years on the dot, and the second set of tires. Even still has the original front pads on the brakes, but due to my real easy driving and feathering them coming up to stop lights, trying not to let the stop/start system engage at full stop, and have been doing an excellent job in timing lights and breaking one law by doing 'rolling stops' at stop signs with no cross traffic in sight. I'm a person that drives a vehicle until it rots down, like I did my '84 Toyota diesel pickup that I put over 800K on it until finally the box frame under it rusted in two, forcing me to park it forever, with the engine still running in it. And with this car I'm shooting for the same mileage before it falls apart just from so many miles on the body.
