Go see Billy Willis!
We had the pleasure of working with Billy Willis. He was so knowledgeable and placed zero pressure on us. It was by far the easiest experience we’ve had. We couldn’t be happier with our 2022 Tucson or with the service we received from Billy!
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.

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.

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.

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.

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.
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.

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.

Honestly I am 65 years old bought 40 vehicles in my life
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.

Best car buying experience ever!!
Ryan helped my daughter make her first adult car purchase. He went above and beyond to make the car buying experience a fantastic experience for her. Everyone there were so friendly and down to earth with easy going demeanors. I would recommend them to anyone purchasing a car!!
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!

Best salesforce of any dealership that I have ever worked with. They met all my needs and I love my MKZ
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.

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.

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.

I purchased my vehicle from Keith Key and the process was very easy and he was professional. This is my second vehicle from Weber Chevrolet and ALL the staff are professional and friendly. They have a GREAT TEAM here and always will recommend this dealership. When I took delivery of my vehicle I noticed more people in the dealership and it speaks volume; people are trusting them. I would definitely purchase again here. Cuddles also to Anthony in the finance department and Brent the manager!!!
The hidden gem Buick Encore GX
I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.

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.
I love my 2018 TourX.
I have a 2018 TourX which I bought new on the early months of 2019. At the date of this review, I have put only 20,000 miles on this car. I am not a connoisseur of high end cars, but I do know when a car is fun to drive, sporty and practical. I am getting the best bang for my bucks with this car. With limited production and stunted promotion from Buick I rarely see any on roads. It's a shame.
