As usual, very good service. Chad Boxdorfer was there as soon as I got out of the car. He was very polite and courteous. Got the car serviced and ready to go in the time he told me. Dave H.
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 had nothing but good experiences with Dean Team
I have had nothing but good experiences with Dean Team Volvo in Maplewood. I took my last car there for years for service. Yesterday I bought a 2022 S60, dealing with Fred Williams. We had a pleasant time test driving and negotiating a fair price. I will continue to do business with the.
Best ride for the money!
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!

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.

My husband and I have purchased 2 cars from BBC and we’re very happy with our cars. Tyler was great to work with!
Our favorite car in over 4 decades of ownership.
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!

The reason why I am writing this is because I know the mileage is off because there is no way I can drive 100 miles in the city in one day it's not possible. This is a complaint for me because I feel it needs to be looked at.

Thanks Brian, Greg, and Jill.
On Saturday 9/14. We made a good decision buying a used car from St Louis Hertz. The staff was very friendly, concerned, and helpful. Expect a few minor scratches on the these 2 to 3 year old cars but, you save about 1/3 off the price of buying a new car. Still waiting for our sales tax check which was financed into our car loan but, they did say it would take about 3 weeks to receive. We should get the check before our temps expire. Five Stars for this car sales.
This is my 3rd Buick.
This is my 3rd Buick. Loved my LaCrosse and just now upgraded to the Invision Avenir. Very satisfied with the look and upgraded options. Performance is a bit less than my LaCrosse with the V6 but adequate.

Extremely easy buying process
Been looking at used trucks for some time. Trenary in Troy had a vehicle that I was interested in. Contacted the dealer, asked if truck was still there and set up an appointment to come take a look. My salesman had the truck up front and ready for me when I arrived. The entire process (including finance) went very smooth and I appreciate that! Thanks again!
no reason to complain
Bought this Encore about a year ago its a 2015, we have driven it daily and just cant find a reason to complain. Its not a race care with its1.4 engine so don't expect it to be fast off the line or on the highway Good on gas handles well, again its not a sports car, just a reliable get around vehicle, one thing very small cargo area

Not super high pressure sales process
Had car salesman Hunter that was extremely helpful in finding a used SUV for my price range. Showed huge variety and among a variety of brands and even let us drive home to see if it'd fit in garage no problem. Price was acceptable and car we got was great! Highly recommend Hunter as salesman as he was more than accommodating to get the car we wanted.

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 .

Everything was great from a service prospective. Took off a star for the 3% credit card fee. Service is not cheap at the dealer and to tack on an extra 3% is unnecessary. In addition I have a GM credit card and to charge an extra 3% at the dealer pretty much makes the card useless. I?ll probably just cancel it

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

Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.
Who said that a family needed a Suburban vacation
The exterior is sporty. The placement of the vehicle's features are well placed. All three rows give even tall people room, such that they do not feel confined. With four adults and a toddler, we were able to have enough space to carry all planned luggage and snacks for a 2400 mile round trip journey. With all this space, I can still get this vehicle inside the garage.

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.

Best car buying experience ever!!
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!!
Rides like a living room couch
I had the car for about a month and I love it. It rides like a dream. The only thing I don’t like is the center console doesn’t have adequate storage, it is very small and the lighter outlet is inside on the bottom so you really can’t store anything in there.

Good and easy people to work.
Good and easy people to work. Duru was so helpful and kind. They help us to know everything we wanted to know and be safe on the road. Thank you guys.
Yes! I will eventually drive this gem!
I can't write too much about this vehicle. The shop has had it longer than me. There seems to be an "out of balance" kind of shake when the vehicle reaches about 25 MPH. I have no doubt that the service team will find and correct the problem. I purchased this vehicle based on the fact that my mother had a Somerset and lent it to me for a week. That car was very comfortable and I knew this Enclave would live up to those standards. The SUV comfort was off the charts compared to that Somerset. For the short time I have driven it, I was pleased. I hope the shop finds the problem soon. I miss the comfort
