Used Buick cars for sale near St. George, MO under $20,000

I purchased a 2024 Honda Civic Sport on saturday and I had a very pleasant experience with the sales rep, Michael Comley. He was extremely helpful throughout the entire process and gave me a very fair deal that stayed within my budget. . He took his time to explain and answer all my questions.I highly recommend Mike.

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.

Colton was absolutely great with the way he handled his self. Great to deal with.

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 felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

Really like this SUV! Wanted more room than my Encore. Has everything I need! Good feeling when friends tell you how much they like the ride and the looks! Wife now driving the Encore, and she loves it!

We worked with Chris Bittick (Chris gets 10 star's) to purchase our Blazer. He was awesome. Very professional, knowledgeable and friendly. He made the experience very enjoyable. Jim in finance was great to work with also. Want to give a shout out to Max too. Over all, great experience. It had the WOW factor.

I’ve had my 2019 Buick Envision since January of this year (2023). We were traveling from GA to MS today and for the first time ever after hitting a bump two different times (a couple hours apart) our vehicle started vibrating and shaking terribly. Very concerning.

Best experience I've ever had buying a car. Great people to work with. Bob Reasoner and Cameron Brodeaux were great to work with. I will definitely buy from them again.

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.

Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.

The interior features of this car are unbelievable! If you have kids this car is a no brainer. The interior layout is a great use of space and having 3 kids they now call my car the LIMO! So many options for charging, WIFI, navigation, we have the built in screens in the headrest, nothing to not like so far!

Recently bought a Sienna with David Bell and had a good experience. He was professional but not pushy and felt we got a fair deal. Would recommend.

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!

Very helpful and eager . Nice dealership with a good selection of cars and trucks. They even stayed past close to get the deal done for us.

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.

Thank you John!my granddaughter loved her car.Very satisfied customer.I'll be back!

Perfect car for my Real Estate business. Ride smooth, plenty of interior room, looks like a nice car and has many features. Great car for the value in money!

Working with Milan Venezia at Genesis of Saint Charles was honestly one of the easiest car-buying experiences I’ve ever had. He made the whole process smooth and stress-free. It went so well that when my fiancé said she was thinking about getting a new car less than a week after I purchased mine I didn’t think twice—I called Milan right away. From start to finish, he was super helpful, honest, and even funny at times, which made the experience that much better. Even the finance guy was cool and easy to work with. And I thought it was pretty cool that a concierge walked me through all the car’s features before I pulled off the lot—great touch. If you’re looking for a dealership that’s honest, has great service, and a clean, welcoming vibe, definitely check out Genesis of Saint Charles and ask for Milan Venezia. You won’t regret it.

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.

They were so friendly and helpful. They take care of their cars. Will go 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 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.

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!!

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. ❤️

James was great! He provided me with all of the information I inquired about regarding the 2012 BMW Z4. He even provided me with phone numbers for a BMW dealership close by and an auto shipper. Thank you!

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.

We had a Trailblazer before, and this time we tried the Enclave. Rides like a dream and very spacious inside! The engine is so quiet I don't even hear it running. We just bought it so I'm hoping it keeps on delivering!

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

The SUV meets all my expectations. Very happy with the quite ride, safety features, quality of the vehicle's interior and exterior, and the 7 passengers the SUV accomadates.

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.

I purchased this car new i have the panoramic sunroof. It leaked the year after I bought the car was repaired under warranty. Last month the roof started leaking again. Cost a fortune to fix as i also needed the roof shade as that was water damaged. I love the car. But do not get one with a panoramic sunroof.

My advisor Brandon is always helpful in my service needs. He always remembers me and greets me with a smile. When here I feel like I'm with 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.

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.

Great Dealership to work with. Very efficient car buying experience. Would do business with them again when the time comes.

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.
