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.

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 husband and I recently bought a Dodge Ram from Colton and we had the most pleasant experience! He got us in the truck that met all of our needs within the first 10 minutes. He answered all of our questions, explained the paperwork thoroughly, and made the overall process of buying a car completely painless. We are definitely repeat Federico customers!

Only owned for 2 weeks. So far a good ride. Can’t speak to reliability as haven’t put many miles on it. Looking forward to doing so.

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.

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.

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.

We love this car. Drives well. interior has a luxury car feel. my husband and i are both tall and a little heavy and there is plenty of room in both front seats for us. you do need to have light weight, slightly shorter friends for the back seat. the only drawback i can even think of is there is not a ton of room for multiple suitcases if you are picking up another couple at the airport. other than that, this is a great auto. we have had it for 3 years and have not had one single problem with it!!!

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.
For the money you can't do much better.

Wonderful thank you Fred Willams and team for the amazing experience ❤️❤️,Im so greatful you guys are wonderful
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!

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!

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 .

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.

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.

Gorgeous car with ST trim
Small but fun. Bought this and drove for six months ultimately trading it in on a bigger vehicle because the seats weren’t wide enough for my husand. Zero issues with it. Loved the look of it (had an ST) and appreciated the safety features. Really thought it was peppy for a little car.

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
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

Rachel Eisele, Tim O’Connell, and Tyler Stevens were
Rachel Eisele, Tim O’Connell, and Tyler Stevens were fantastic. My husband and I were shopping for new car and didn’t have a salesperson chosen upfront. We walked into Bommarito Toyota and were immediately connected with Rachel. Rachel was friendly , professional, and knowledgeable. She answered all our questions and guided us in purchasing a brand new car as well as helping us understand all the benefits and resources we could take advantage of and in getting a good deal on our old vehicle that were trading in. She was clear that the waiting could take up to 4 months (other dealerships had mentioned the same thing too). But Rachel kept in touch and believe you me, she got us a brand new car in 1 month! Better still, she collaborated with Tim to ensure we had all our questions about a new car answered. Tim took the time to help us get acquainted with the Toyota App. It was a new level of experience to see two salespeople working collaboratively rather than competitively. Tyler at the finance department helped us to seamlessly work through financing and was extremely patient with our two kiddos - 1 year and 3 years old. I couldn’t recommend Bommarito Toyota enough. Thanks for your service.

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!
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!
