Used Buick cars for sale near O'Fallon, MO under $20,000

We had a great experience here with Aidan. The whole crew is pretty low-pressure, which is refreshing in a car dealership. I'd highly recommend them to anyone!

So far its been a good vehicle. It's drives and handles well. Safety features excellent. Gas mileage excellent. Hugs the road good. I like the camera in rearview mirror.

James and all of the folks we dealt with were great, professional, and so helpful with helping us understand our car, financing options, etc. We LOVE our EV9!!!

Purchased pre owned with 56k miles. Everything seems to be great thus far. The only thing is I’m not sure the AC actually works as I normally keep it set to the “Auto” function. And when the temperature got up a little warmer than normal it didn’t seem to make the adjustment.

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.

Great vehicle with room for seven and plenty of cargo space. A great motorhome TOAD thru model year 2017. Powerful V-6 engine and smooth shifting transmission.

Excellent buying experience. Jeremy my sales rep and the financing made it a quick and easy process with an honest price. Most of the process was done online and when I arrived we were set to go.

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.

When I purchased my dream car Genesis GV70 from this dealership I noticed how well kept the service area was. I only take my car here for service because it is professional, clean, organized and the staff is amazing. They do great work and often have you in and out in less time than expected. Josh and Brad have been so helpful. Their knowledge and experience is much appreciated.

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.

Very casual and friendly. The salesman had all the history of the Escape, which put me at ease in finding him trustworty.

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.

I sold my SUV to BBC and they were very helpful with handling documents and explaining steps ensuring a smooth transaction! Will call again for future car needs.

We love this car. I've had Lincolns including the Navigator, high end Chrysler vans, "luxury" Fords like the Eddie Bauer Expedition and Mercury Mountaineers and this is by far my favorite vehicle. The Enclave projects luxury and backs it up. We have the Premium edition. The ride is excellent and far outclasses other SUVs we've owned which rode more like trucks. Plenty of room and a 5 star safety rating make it ideal for toting around the Grandkids. We went AWD for Michigan winters and plowed right through deep snow. A little more power and a little better gas milage would be nice but it's worth the trade off. 18 mph city is better than the Buick Regal Turbo we replaced and this car rides better too. I'll take the 23 mpg on the highway. As a 70s rock and roller and 45 year radio industry veteran, I love the Bose sound system. Especially when no one else is in the car! This is by far my favorite overall vehicle in 47 years of ownership. And yes the Kids and Grandkids give it 2 thumbs up!

The whole experience was great. Super friendly. No haggling. Worked really hard to get us what we needed though. Vehicles were in excellent shape! Facility was very nice! Brandon our salesman was so friendly and helpful. We will be back!

Buick enclave great car for comfort and reliability and value Bought this car new And I’ve kept it much longer than most vehicles that I have purchased because it is such a great vehicle. Comfortable to drive in town and on road trips. Excellent for people in my big Shepherd enjoys riding in the back with the seats folded down

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.

Excellent riding SUV. I would highly recommend this SUV. Not bad on gas for a large vehicle. Plenty of space. Very quiet!! Lots of room for big people. ❤️

Jamie was the best, would send anyone to him...very knowledgeable, attentive, and relaxed through the entire process. We will seek him out in the future and send friends.

This car easily met my expectations on comfort and performance. I love the color of the car and the interior. The car is easy to maneuver. Thank you Bryan Koestner.

My car purchase experience with Ryan P. and the experience with the service department's Aaron Barr have been excellent. Both gentlemen have done everything possible to make my new car purchase experience a great one.

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.

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 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!

I usually hate buying cars but the experience I had with my salesman, Kris Portnoy, at Suntrup Kia was great. No high pressure and great to work with. He explained everything about my new vehicle and Kris really knows his stuff. I would highly recommend him if you are looking for a vehicle!

The car is beautiful inside. The seats are comfortable. I have a heated steering wheel and seated seats. The car has an automatic starter. I put high test in engine and the pick up is great. I put gas in the tank almost every two weeks. I love the car and would highly recommend it. Best car I ever drove.

MATT WAS GREAT TO DEAL WITH. HE TOOK EXTRA TIME TO MAKE SURE I UNDERSTOOD ALL FEATHURES. LOVE THE TRUCK AND THE POWER. I WILL TELL MY FRIENDS AND FAMILY.

Very good vehicle. Not that great on gas, but ok for all wheel drive. Lots of room up front, really like the the all wheel drive.

Excellent service, fast process, and very friendly staff. Truly a great experience for a new buyer. I do recommend Angie Flamn!

I bought this used with 26,000 miles in the spring of 2024. I love the styling, interior, and value. My only complaint is that the angle of the infotainment display can make it difficult to see due to reflections, especially in bright sunlight. I love the AWD option, it adds to stability - even in dry conditions. The remote start is handy in cold weather since I now live in an apartment and no longer have a garage. Performance with the optional engine is more than adequate.

Dave took great care of everything! Thorough and courteous throughout the whole experience. Made it a highly enjoyable and easygoing experience! Highly recommend! Thanks again!

Great car for the money. Easy to park and has been very reliable. Would definitely recommend this suv. I love the hatchback and can fit a ton of stuff in the back. Much more useful than a sedan and the back seats fold down.

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.

I unexpectedly wound up leasing a 2022 Buick Encore GX. I have been very happy with all of the features and performance of the vehicle. It is peppy, handles great and is quite comfortable. A small step down in size from a Chevy Equinox and it has worked out extremely well.

I bought this car 9 years ago as an ex hertz car. It had 24000 miles and now it's only got 52000 miles. The reliability is bulletproof so far nothing has ever gone wrong (touch wood). I've owned 33 cars and this car has Honda/Toyota build quality and reliability. The downsides are I find it very thirsty, I've never managed better than 22mpg in mixed highway driving. i find that the car is quite gutless but it's fit for purpose. The resale on these is worthless so I plan to keep this car until it dies. I have other cars but this is still my daily driver.

We bought a Toyota Corolla Cross Hybrid. An excellent and safe car. The sales person, Barb was very professional and patient. She and her coworkers who were helping us to choose the right car for us, were wonderful. I highly recommend this dealer.

I had to replace the water pump and the thermostat housing at only 30 thousand miles. Left me stranded at work all the water dumped out within minutes

I am really grateful for them they really turn my experience around and would come in the near future

Whoever designed my 2919 Buick Encore was the best of the best. My wife and I love this car so much. I’v had a lot of cars over the years this one is the best. It is a great car and I love driving it.
