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.

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.

Everything was great from a service prospective.
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
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.

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

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.

We dealt with Eric as our salesman.
We dealt with Eric as our salesman. He was super easy to deal with and very fair. Very nice guy. We had a trade in and I feel like the value we got was very fair and what we expected. Would?ve given 5 stars except I tried to haggle a little with some extra costs and the sales manager was not having it. She told me to ?pick another car? that didn?t have the extras I was trying to finagle the price on. Told me they were losing money on the deal and couldn?t work with me on price. I ended buying anyway because we liked the car and the dealership overall was one of the more pleasant dealerships I?ve been to.
Encore GX ST What a 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.

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.

Great place for a new Kia
Great experience from the Napleton Kia team. They do not change over MSRP and financing was quick easy and painless. Chris Dixon the sales manager was awesome!
What a nice surprise.
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.

Ms. Mary S. Scialfa
CarMax made the purchase of my vehicle run smoothly, without having to go to the Division of Motor Vehicles. They addressed my concerns promptly and, when new keys had to be made, offered a "loaner" vehicle until the problem was fixed. I recommend CarMas to everyone!
Awesome Encore
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.

Nice luxury vehicle
Worked on one for a friend and this car is smooth and easy to work on. It's big and roomy and very stylish even today. The only thing I seen that I did not like was it doesn't get good gas mileage and it's a V6. Kinda to much weight for a V6 to be pulling but once you get it on the highway it's definitely a cruiser and smooth.

Best car I've owned
I loved my 06 buick Rendezvous CXL. I got it used with 130,000 miles on it . For 6.5 years it got me where I needed to go and I used UT as a work vehicle hauling thousands of lbs. I even got a tow hitch and towed first an 18' trailer then a 24' trailer that I used for scrap metal recycling. It pulled both like a champ. I towed loads over 6,000 lbs with no issues. But all good things must come to an end eventually. I did most of my own maintenence, and let's face it, I'm no mechanic. I don't know exactly what I did to my poor car. It starts up , but that's all it does. I'm debating on weather to retire it or fix it. Mechanics are so darn expensive. And I don't know if I can afford to fix it.

Luvs My Rainier
I have owned my Buick Rainier since 2015 I have had only one issue and that was being able to turn sharp curves or corners...I got stuck in a drive thru window. Had to go over the curb. We removed the front axle so I am not all wheel drive. I only have a rear wheel drive and I can turn on it on a dime. I love my reindeer. A dime
