After intense negotiations we reached a deal that I feel was a descent deal of course I would have liked to have gotten more for my car and given less for theirs along with a few more concessions from them but overall I think things worked out pretty good.

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 .

Above and Beyond Customer Service
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 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.

Excellent Salesman
I discussed the purchase of a 2023 Mini Cooper "S" with salesman Dustin Summers. He was completely knowledgeable of all the features and details of the vehicle. He was always courteous and handled himself in a professional manner. I'm still debating on buying a vehicle, but if I decide to do so, it's back to Dustin Summers I go. Michael Deters

This is a very exceptional automobile featuring many safety features at a very affordable price compared to higher priced vehicles! The car is very attractive and sporty and has earned many admiring comments from people I have met in parking lots. The only drawbacks which might turn off certain prospective buyers are the 3 cylinder turbo engine and the lack of a 4 wheel driving option. Other than that this is a very attractive auto at an unbeatable price!

Prior to purchasing my Buick Envista, I had done quite a bit of research and I found that much of what was said was misleading. It's performance I think is very good, realize you are getting a 3 cylinder turbo engine, but for what you get and honestly what you need, it is excellent. I purchased the S/T model and it is a great looking car and I receive great comments about it all the time. I strongly recommend for the money you can't go wrong and will be vey happy with your purchase.

2024 Avinir, Quiet and full of pi55 and vinegar,
2024 Avinir, Quiet and full of pi55 and vinegar, definitely and defiantly punches above it's class. Full of top shelf safety features and driver aids. Not a fan of the engine stop/start feature but it has its place I suppose. Coming from a competition audio background the sound system is very clean and bright but lacks any substantive sub frequency response, well see what the aftermarket will have for me. First tank of fuel from the dealer must have been low grade 87 octane and the engine just wasn't liking it. Inconsistent low end torque would put the car into a weird spot on the turbo curve, not as smooth as it should be. The next full up I put in was 89 octane and the difference was stark, a much smoother run up to the turbo power band. So don't penny pinch on the fuel use good brand @89/91 octane (13 gallon tank...). Oil changes are super easy. The filter and drain plug are placed, IMHO, to take away any excuse for not keeping good oil on the engine! The tires size is 19" so the handleing is great but overall ride could be better with 18". My son has a Trax Active and it has a bit better road manners than my Envista, not so much felt road texture. YMMV. Super value and right sized commuter, spend any real time getting to and from work a you will appreciate your decision to get one of these for you self!

Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.

Buick Lacrosse Avenir AWD is a fantastic car!
We recently replaced my wife's car with a 2019 Buick Lacrosse AWD in the Avenir trim line and it has proven to be a great car. The must-haves were AWD, ventilated seats and enough room. This resulted in cross-shopping a LOT of different brands and vehicles that normally would not be compared. I was leaning toward a one of the big 3 Japan makers but she wanted to give Buick a chance. In the end we found this specific car listed in Auto Trader at a local dealership. It checked all the boxes and had more than enough high-end features to satisfy without having to make the large price leap to Cadillac. The ebony and chestnut interior is fabulous and the interior is made of high-quality materials. GM interiors have had a long reputation for cheap materials but not this one. True the lower door pocket panels are hard plastic but virtually everything you actually see and feel while driving is great. The switch gear all has a good feel and the controls are pretty intuitive. Even the shifter that has gotten some flack in some reviews is actually easy to get used to. The power and power delivery from the 310 hp 3.6L V6 and 9 speed transmission is great. The only small issue is some lag after stomping on the gas at speed. But once the power comes on it comes on hard and the overall throttle response is great. The brake pedal and feel is fantastic - smooth and linear with no gabbiness. The performance is really impressive especially for a full size sedan. The engine auto-shutoff is not intrusive but it cannot be disabled. The handling with the 20" wheels and adaptive suspension is incredibly impressive. Sport mode adds some weight to the steering and firms up the ride a bit. I was surprised by the extremely good predicted reliability rating that the Lacrosse had (higher than the Toyota Avalon) so that eases my mind about going with this particular GM product. Yes, this car, with every possible option on it in the Avenir trim, gets perilously close to the price of some offerings from the luxury brands but I don't care. It has AWD and most of the others don't offer it.

The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!
The hidden gem Buick Encore GX
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.

My wife and I are very pleased with our 2024 Encore GX
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

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.

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.

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.
