Used Buick cars for sale near Frontenac, MO

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!!

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.

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.

Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.

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.

Quick oil and lube service. Previously purchased 4 tires. Prices were the best in the area. Competitive with the discount places and you get dealer quality service.

Was looking for safety and security in a suv Comfort for neck and back were important this particular model goes above and beyond. Ride is smooth and quiet with what engine doesn't have in speed it has in hidden torque in motor. Black on black with black grill and rims with crushed glass in the paint, so many compliments especially how masculine looking the vehicle is The dealership Garber of Fort pierce has been amazing from sales to service to accessories Best purchase I've made in years highly recommended

My experice on the most part was great and with the experience I had the last two times seemed tough but wasnt bad at all

Traded my Rogue for a 2020 Buick Enclave and I am loving it. It is comfortable which matters to me since I am older. I don't know if it would be that popular with a younger generation but for long trips I think even they would like it, especially if you have kids. It is great when traveling with our dogs and we could sleep comfortably in it if we decide to stop at a camp site. I do wish it had some standard things on it that my Rogue did. The seats are more comfortable than the Rogue. I wish the cruise control automatically adjusted the speed. I wish it had a Lane departure warning.

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.

Great experience with Bruno and Columbo when I bought my Denali. I was able to do most everything online and it was very easy and quick at the dealership. I drove 3 1/2 hours for this great deal and I will definitely shop here again.

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.

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.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

I have driven my 2025 Buick Enclave Sport Touring almost 9k miles and I am beyond happy with the car. The car is very smooth, comfortable, beautiful and economical. I do both city and freeway driving and so far, my MPG average is over 29 miles, getting about 580+ miles to a tank of gas! My 2025 Enclave drives so much better than the SUV I used to drive that had a V-6 engine and gets over 10 miles more per gallon of gas, on average. I have more than enough room when transporting family members and/or my (3) dogs. Everyone enjoys being a passenger in my Enclave.

Kelly is awesome helped me trade my xxx for an amazing truck. Love it thanks

I love my car drives and handles beautifully so comfortable good gas mileage also would highly recommend this vehicle to anyone and it has a great warranty.

Shawn did a great job working with us to get us the terms we wanted.

As over many years Buick is in the background, however I have owned both, and the Buick outshine the Cadillac ever year. If you want to impress other 's and spend money go with the Cadillac if you want to enjoy your car buy the Buick. That said start looking at the envision on up

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.

Have had this car for a month. Everything is so well laid out and the MyBuick app is so easy to navigate. The mileage is fantastic. This is my first new car (ever) and my 3rd Buick overall. I love it!

2014 Outback manual transmission and rear differential oil change was performed. It was done quickly.

For the money you can't do much better. Quiet, sleek and has lots of options available. Has plenty of room and storage for this class of car. Love the AWD version as I live in a part of the country that gets a fair amount of snow.

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

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.

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.

My wife and I are very pleased with our 2024 Encore GX purchased used w/ only 2500 mi on the clock. The Encore GX is one of the current Buick lineup of 3 small SUVs for about $25k; I suspect these hidden gems are unknown to many Americans. Unfortunately Buick's focus on China has resulted in the Buick brand being all but forgotten in the US. The NHTSA has given a ***** Overall Safety Rating to the 2024 GX. I have one negative with the Encore -- I'm 6'-1" and the Encore is small for me. Some call the cabin "surprisingly roomy" for a sub-compact suv. Truth be said IT'S JUST SMALL. Likes * 1.2L Turbo engine surprisingly strong in city driving * Entry-level luxury at a moderate price * Fun to drive (some call it boring) * Lots and lots and ... of safety features * Excellent mileage (30+ mpg) for an ICE SUV * Sits up high (as a SUV should!) due to 18" wheels * Quiet cabin due to Buick's QuietTuning technology * Heated seats, steering wheel, outside mirrors * Physical buttons/knobs for radio, climate controls -great * Power hatch/liftgate w/ kick plate - very handy * Traction & Stability control Dislikes * 1.2L Turbo engine is somewhat challenged on the highway * Design same-same as every other small SUV on the road * Digital Speedo and NO Tach; I prefer the real thing * Seats are narrow, hard and uncomfortable on long trips * Road noise is worse than expected for a Buick * Small cargo area w/o rear seat backs down * Insufficient legroom in back seats * Insufficient rear headroom for tall persons * AM/FM/Satellite radio difficult to program * VERY sensitive brakes and accelerator

My salesman Aaron Voege was excellent,courteous and I will recommend him to all my friends.. He made the transition from my Altima to my new Rogue perfect. Thank you Aaron..

The Encore 2024 GX ST is my second GM car, which has truly impressed me. I've driven various vehicles, including Honda, Infiniti, Toyota, and Saturn, but the Encore GX truly stands out. Its sleek and attractive exterior design caught my eye immediately. On the inside, the elegant beige leather seats create a luxurious atmosphere, and the state-of-the-art infotainment system adds to the overall appeal. The exterior has been significantly improved with the modern Buick logo, giving the car a more contemporary look. One of the most outstanding aspects of the Buick Encore GX is the driving experience. Navigating the vehicle is incredibly easy, and when you press on the accelerator, the car effortlessly gains speed. This is in stark contrast to my previous experience with the Toyota RAV4, which struggled to accelerate quickly. Overall, I'm thoroughly pleased with the Encore GX and would highly recommend it to anyone in the market for a new car.

This review is in full support of Clement Hyundai – a dealership located in Wentzville, MO – which has shown remarkable, above-and-beyond customer care. At the end of our leasing period for a 2020 Palisade, my wife and I purchased the car outright. The transaction was handled smoothly and thoroughly by salesman Jeremy Null. Following that, our car needed to go through a few inspections for the warranty coverage. In doing that, there was a faulty wiper installed -- requiring the car to go back in to get it fixed. While this could have been a very frustrating experience – as we live more than 30 miles from the dealership – the team at Clement Hyundai went above and beyond for us, recognizing the inconvenience. Especially Jeremy and General Sales Manager Patrick Piper. They picked our vehicle up and delivered a loaner, as well as provided other coupons etc. to make up for the situation. When my wife realized she left my daughter’s dance recital tickets in the glove box, they drove out to our home to deliver them to us. That’s the kind of operation they run: one that has the customer at the center of what they do. I’ve never experienced such superior customer service from any other local dealership – and I’ve owned BMWs, Audis, Toyotas, Hondas, Fords and other makes and models. Clement is a first class operation and should be super high on your consideration list for purchasing a vehicle or getting service.

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.

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

I love this car and it’s loaded with safety features and it’s pretty fast, a fun to drive car. Also pretty comfortable so if you’re looking for a nice car get this one.

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.

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.

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've driven cross country several times without a problem. It handles the road very well, even in high winds. It has ample storage and everything is easily accessible and in reach of the driver.
