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.

Buick enclave
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

Mini of St Louis
Prompt response to my interest. Was given several choices of a mini that fit my needs. Sam Hall, the salesman, was very helpful and put me in the car I love!
I have had no real problems, except maybe the cheap tires
I have had no real problems, except maybe the cheap tires they put on when its new. 23,000 miles and down to the wear bar. Sometime the info screen is frustrating to get the right pressure to find songs with the music channel I have. I do worry about the short warranty. 3 yrs 20,000 miles which is over. I cant believe that I overlooked that. I worked at GM for 8 yrs so I got the discount and that was why I bought it. If I had to do over I would by one of those Asian cars with 10 yr 100,000 mile warranty. Though I have had no problems so far. I only put about 7500 miles a yr on my car. I have 23500 now.

Matt is the kind of dealer you had back in the day.
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
Fate..? Maybe.
I was kind of forced into my 2022 Envision during the inventory crisis post covid. My Alfa Romeo Giulia lease was totaled. I lost the market equity as Ally being the lessor is entitled to retain all over payment. I needed a vehicle quick. Upon arriving at my local Buick GMC dealer I asked what was on the lot long enough they wanted to move. The answer was a Preferred awd Envision in Burnished Bronze. I bought it, was surprised with the "premium sound system" (not Bose). Love the quiet smooth ride. This 2.0 is not the Alfa's 2.0 that is for sure, but I have had no issues getting around or through slow traffic. All in all... I was, and continue to be, a year later impressed. Well done Buick, just wish it had LUMBAR.

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.

I recently had the pleasure of purchasing a car from Suntrup Kia South, and I can’t express how satisfied I am with the experience. Despite being a thousand miles away, their professionalism, transparency, and warmth made me feel right at home. From the moment I connected with Moe Saad, I knew I was in good hands. Moe exemplified the epitome of a top-notch car salesman, providing me with reassurance and guidance every step of the way. My search for the perfect EV9 led me to many dealerships, but none matched the integrity and authenticity of Suntrup Kia South. Moe and his team went above and beyond, offering red carpet treatment without the need for an actual red carpet. Even while under the weather, Moe ensured a seamless transaction, passing the baton to Dzenis, who continued the stellar customer service. From start to finish, every detail was meticulously handled, including a thoughtful conversation with sales manager Dave, who ensured my satisfaction was met at every turn. In an industry often plagued by deceit and gimmicks, Suntrup Kia South stands out as a beacon of honesty and excellence. It’s rare to find such a level of service and transparency, and I can confidently say this was the best car-buying experience I’ve ever had. Despite the distance, I’d make the journey again without hesitation. If you’re in the market for an EV9 or any vehicle, do yourself a favor and visit Suntrup Kia South. You won’t be disappointed. Hats off to Moe, Dzenis, Dave, and the entire team for exceeding expectations and setting the bar high for customer satisfaction.
My only complaint is that I cannot seem to close the door
My only complaint is that I cannot seem to close the door mirrors. Small complaint and not really a flaw but cosmetic. The car is amazing. It has plenty of room and acceleration. It is comfortable and luxurious too.

Traded my Rogue for a 2020 Buick Enclave and I am loving
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.

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.
Buick is bringing sexy back.
Buick is bringing sexy back. I have had two friends say it looks like a Porsche and an Audi. The Sport Touring model is the sexiest car I've ever driven. Super comfortable with lots of head and leg room. The seats are ergonomically designed. The dash is a technical marvel. Runs great and even gets 30 MPG on the highway

This 2024 Envision Avenir has more than satisfied my expectations. The car is peppy under most conditions even with the 4 cylinder turbo. The large screen on the dash provides a lot of options of what you might want to show and it is easily changed. I believe that it has a very nice look and feel in that inside and nice looking on the outside.
