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!
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!!

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

Josh Greenlee (service advisor) always goes the extra mile to insure customer satisfaction. Needed a emissions inspection for a registration renewal. Had forgotten to make an appointment last week. Called Josh comings off a holiday week and was accompanied that afternoon. Outstanding as usual.

Ron, and the entire staff are first class!
Ron, and the entire staff are first class! My wife and I flew down from Minneapolis. Ron picked us up at the airport. We took the vehicle for ride & within an hour and a half, we were on our way home. The smoothest transaction I've ever had buying a vehicle.
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.

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.
Its a decent car, but on a car frame.
Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

A very special Thank You to both Chad Sigsworth (Sales
A very special Thank You to both Chad Sigsworth (Sales Associate) and Patrick Amann (Service Associate) who both assisted in the replacement of my engine. Both gentlemen were dedicated from the begining to the end of this replacement. They both stayed right on top of things and kept me well informed until the job was completed. I will always purchase any future vehicles through Dave Sinclair due to their honesty, dedication, and treatment of their customers. They have one of the best staff I ever had the pleasure of working with. Keep up the great work. Sandra Hearn

Thermostat only other repair/replacement.

Great experience from start to finish.
Great experience from start to finish. From the salesperson, Ryan, to the finance manager, Curtis, we were listened to and treated graciously and respectfully. We would highly recommend Lou Fusz when looking to buy a new or used vehicle. We love our new car and have peace of mind that our purchase will be protected by their excellent Service Department in the future!

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

We just had our 2017 Ford Escape in for an oil change and its annual checkup. David Farmer the Service Advisor did an excellent job of putting up with 2 old cranky people who complained a lot about various little things. He is a kind young man that gives a good impression of your service department.

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.

Blaine was very professional and helped us buy our new car. Thanks, Blaine for everything!
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.
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.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

Tony Franks was a wonderful sales person.
Tony Franks was a wonderful sales person. He was very polite, easy to talk to spending alot of time with us. He was very informative with our questions regarding the Traverse we bought along with the questions we had about the process of buying the vehicle. He also demonstrated how the dashboard operated and answered the questions we had about all of the new computer board which is alot different with our current vehicle. We did not feel pressured and felt very confident with him. When we signed the paperwork with Brian Risk we also felt relaxed and nonpressured. He was very friendly and informative. He also rook the time with us while we decided on our loan and which extended warranty we wanted. This is our 4th vehicle we bought there since 2010 and hope to buy again. Overall our experience with this purchase was efficient with knowledgeable staff that made us feel comfortable.
