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.

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.

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.

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.

My overall experience at Dave Sinclair Lincoln has been amazing. My sales rep Dee-Davis. She did such an amazing job with the whole process. Great communication. Dee got me approved in minutes and I was out the dealership just as quick. I truly recommend purchasing a vehicle from this dealership and also Dee-Davis.

The vehicle was great EXCEPT for the shifter which was the worst type EVER that GM designed!! I had family that could not figure out how to use it!!

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.

rides like a dream easy to park lots of room inside can carry whole family or put the seat down for construction load. It has a beautiful body and looks important on the road

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.

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!

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!

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.

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.

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 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.

Best dealership experience I've had. Sales and financing were helpful, never pushy, and extremely quick with the process. I'm so happy with both my new car and my experience.

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.

Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.

This is by far the best car for your money, I bought this car used with almost 40k miles and now it’s at 110k miles in about a year and a half. I drive 100-300 miles a day and this car gets around the same gas mileage as my old Hyundai sonata. This car is driven through heavy traffic in Washington DC and the rural countryside on a daily basis and can handle just about anything. This car drives and feels like a Mercedes S class. I travel around the area and I couldn’t think of a more comfortable car to do my job in. I never have to worry about reliability. The only con with this car is that an oil change is about $120 wherever you go (DC Area) and my fog light was knocked out by heavy snow ($25 part). If you’re researching you should definitely buy this car.

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

I had the car for about a month and I love it. It rides like a dream. The only thing I don’t like is the center console doesn’t have adequate storage, it is very small and the lighter outlet is inside on the bottom so you really can’t store anything in there.

Tyreese listened to my wants and even though my initial choice sold prior to my arrival, he found me a better option. He was very knowledgeable about the cars features which made me love my car even more.

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!

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.

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.

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.

Amazing staff and environment. Best car buying experience ive ever had. I cant recommend then enough. I had a bad experience at another dealer and that thankfully landed me at Frank Leta. Dont bother going anywhere else. This is THE dealer to go to.

What a superb automobile. This is what I have wanted in a long time. It has more bells and whistles than I really need but it is very nice to have them. Everything I marked above is definitely true and more. I would highly recommend this auto to everyone interested in buying one. Believe the right ups on this auto that others have also made.

Matt is the kind of dealer you had back in the day. I enjoyed the short back and forth we had with numbers and the entire dealership left us with needing nothing, they took care of us further then we actually needed

ABSOULTLY LOVE THIS CAR HAS EVERYTHING YOU COULD ASK FOR. VERY QUIET INSIDE FEATURES FEATURES FEATURES ARE ABUNDANT I AM SO GLAD I BOUGHT THIS CAR. WE DID ALOT OF SEARCHING AND THIS WAS THE ONE WE KEPT COMING BACK TO

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.

As always the service and people at Gastorf are fantastic. They keep you updated as the car is worked on and always take the time to listen.

I was looking for a car that had great gas mileage and still had plenty of room with a hatchback and was fun to drive. I definitely found it with the Buick Encore. It has been great in the winter with the all wheel drive also. The back seats fold down which I really like so you can fit a ton of stuff in the back like camping gear or shopping treasures. It has excellent connectivity with the cell phone with bluetooth or a usb cable. It has been easy to maintain also and have just had to do oil changes and has been super reliable. I would recommend the Encore to anyone I know and think that what you are getting for the money is hard to find in any other car on the market today.
