Used Buick cars for sale near Castle Point, MO under $20,000

Employee was super helpful and went out of her way to help us get a new car

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.

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 car for almost 2 yrs & it’s been very reliable & comfortable especially on long trips I would definitely buy again very happy with it.

Turns out the Manager Andrew is a True Gentleman. Treat him with respect and expect the same.

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.

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 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 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 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!

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 2016 used with 55k on it 3 years ago. When first purchased had transmission torque converter issue but got transmission replaced under warranty through dealer and has been amazing car since with no issues. Pretty sharp looking inside and out wish wasn’t so mini van shaped but honestly that’s how we use it. Kids love the DVD player. Definitely happy overall.

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.

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.

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.

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!

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.

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.

Simple, helpful. Scott was very professional, polite, and overall pleasant to work with. I recommend him highly

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.

Tanner salesperson and Justin finance. Both knowledgeable, helpful and friendly. No pressure to buy a vehicle. Worked with me to find optimal savings and kept in touch with me on sll wuestions

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.

It was amazing. The salesman understood my needs and wants and financial situation and found me the perfect car

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.

Excellent service by the whole team. They worked on my car was finished sooner than I expected. The service manager was outstanding. The work was done professionally and the car was even washed. I highly recommend the dealership. The waiting area, features, free water, free coffee, comfortable chairs, and tables and very clean and bright

I have not had any problems with my Encore. I drove it to Nevada, California, Arizona, New Mexico, Texas, Kentucky and Arkansas and have not had any problems with it at all. I have had the standard maintenance on it, Radiator Flush, Oil changes and put a new battery on it in 2022. The battery it came with lasted 6 years, can't complain about that. And I just put a set of tires on it too. I am very happy with this model and would recomend it anyone looking for a GREAT SUV.

Initially I was told there were not appointments available for about a month, but I left my car and they worked it in anyway -- they thought they could work it in in about a week and a half, but it only took them 4 days.

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.

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.

Dearrell was a great salesman. Everything was good fast past. I highly recommend you buy a car from here. They will work with you and find the of your dreams.

My Name is Gayle McClure, 1st I’ve been taking my car to Sunstrup over 10 years. The technicians and service advisor, Ian, and Scott are the most knowledgeable and patient people with their customers. I trust their advice, they always tell me the truth. I would recommend anyone who ask me to trust Sunstrup.

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

Wonderful thank you Fred Willams and team for the amazing experience ❤️❤️,Im so greatful you guys are wonderful

The Encore offers a very quiet and smooth ride. It has the get up and go when needed and handles really well. Drivers seating position is great for tall or short people but the seats aren't geared towards (wide) people, no disrespect intended. The car isn't very wide and the interior shows it. Driver and front passenger must share the one armrest on the driver's seat. A/C & heating knobs are not illuminated makes them hard to see at night. Back seat room is OK. Storage area good for groceries but not much else unless you raise the rear seat and lower the seat back. Doing this we were able to get a new mower in the box inside without any problem. Almost 30,000 miles with only regular oil changes and tire rotations. No mechanical issues at all! One of the best cars we have owned. Not to mention we bought it new while offered at $10000 of of list price!

Great to work with. The access and style of the location are very weird, but buying process went smoothly. Negotiation was fair, and the F&I office experience went great also-no pressure.

I bought 2014 Premium AWD used w, 30k miles and odometer now reads 179k. The car has been very reliable , I have replaced the water pump, timing belt, and done brakes and oil changes, I also fixed the manifold/valve cover issue. These were all normal Repairs . I am pretty good with maintenance, so that is key w this car. If you just drive it, don’t change oil or fluids then like any car you will have problems . This one has been very good .

This review is for Jimmy, one of the sales associates here. I spoke with him about my options for trading my vehicle. He was very knowledgeable and helpful. Now that I know my options, I’m looking forward to working with him in the future!

I love my Encore. Good size. Easy to handle. Great gas mileage. Nice looking SUV. Sporty. Love the hands off phone. Large screen. Large windows - great view. Maneuvers great!!

Paige W. In the AUFFENBERG Service Department does an excellent job. She’s friendly, knowledgeable, and efficient. She is a true asset to AUFFENBERG.

I leased this 2017 Encore in 2017 after the lease was up I bought it. Now in 2024 I am just putting tires on it. I put a new battery in last year. That's it! I change the oil. I have read the bad reviews and am surprised. To be fair I drive in town and 6000 to 7000 miles a year.
