The dealership was great.
The dealership was great. Jack, Aurora and the rest of the staff were very nice and helpful
Happy with my 4th BMW
The car performs well on the highway and has significant acceleration for Interstate driving. Ample room for vacation trips to take luggage and golf clubs.

Thank you so much Justin for helping me with my new Audi
Thank you so much Justin for helping me with my new Audi q5! Very much appreciated
Love It!
Love my car! Got the Metallic Carbon Black with dark front grill and Oyster leather interior. Fits me like a glove. Easy to drive and handles very well. I do not care for the auto shut off at stop lights. They couldn’t get the chip to delete that so it is what it is. If I put it into sport drive mode, it doesn’t do it. Also couldn’t get passenger lumbar, due to no chip, and I do miss that. Great on gas too!

Couldn't be happier
My husband and I have bought cars in the past, and were always left with a bad taste in our mouth. Biener Audi in Great Neck was the exact opposite experience. They did not try to push us into buying, they were considerate and extremely thorough through the entire process. We went to the dealership to test drive the Audi Q7 and did not intend on buying the same day. We wanted to get as much information as we could before discussing it and making a decision. Our salesperson, Danny, could not be more friendly or accommodating. He answered all of our questions and guided us professionally. When we advised that we would not be buying that day, he was understanding and did not make us feel pressured or act like the typical salesperson. The next day, we went back to the dealership and bought our new truck in a timely manner. Our 2 year old was with us through the entire process and everything still went very smoothly. Furthermore, the facility is extremely well kept. There is ample space for customers to sit and wait. We eventually went and sat in the service area where they offered complimentary drinks and snacks, and a wonderful woman came by to give my son a coloring but and crayons! Our family could not be happier with our first experience buying a luxury car. We know we made the right choice with Biener Audi.

The car buying process can be hassled and stressful, but I had the most pleasant and happy experience dealing with the team at Bridgeport BMW. If you’re looking for a prioritized experience vs predatory experience, then it is worth giving Bridgeport BMW your time and your business. Big thanks to Zashley, Paul and Charles, I appreciate your time, patience and accessibility. WJ

I had an outstanding experience at Power Motors!
I had an outstanding experience at Power Motors! From the moment I walked in, I was greeted with friendly faces and a no-pressure environment. My salesperson, ivan, was incredibly knowledgeable, patient, and genuinely cared about helping me find the right car—not just making a sale. The entire buying process was smooth and transparent. They took the time to answer all my questions, walked me through the financing options, and even followed up after the purchase to make sure everything was going well with the car. I ended up driving away in a vehicle I absolutely love at a price that felt more than fair. If you're looking for a stress-free car-buying experience with people who truly go above and beyond, I highly recommend Power Motors. I’ll definitely be returning for my next car!
Love at first drive
I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

Great buying experience. Ivan was awesome and very informative. Will definitely recommend to family and friends.
Very clean and smooth car!
Plenty of space. Smooth when driving on the road with pot holes etc. The panorama roof is very nice to have as it opens up the inside of the car and let’s so much better light in. Creates more space.

If you need a nice luxury car come to power motors east!
If you need a nice luxury car come to power motors east! Angel Cruz is the guy to speak to!!!
Awesome!!!
I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

fantastic experience
Kudos to the team for a fantastic experience. The low finance rates made my decision even easier, and I'm thrilled with my new vehicle.
Sedan vs SUV
Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.

Good Service Team
Routine maintenance was fast and hassle free would come back again for service. However, the sales team could learn a lot from the service team in terms of professionalism, timeliness and good service. Service Team A+ , Sales Team F-
Nothing like it.
Nothing like it. Definitely a sleeper. A rocket on steroids. This SUV is race car built for the track but made for the road. It corners wonderfully especially on hard tight corners. It has a sport suspension which makes it ride very harshly on runflats but softens up on Michelins. I didn't buy this suv for gas mileage rather I bought it for fun. Yet it averages 21mpg around 75-80mph. The seats fit like a glove.

I brought a 2019 Mitsubishi Mirage ES back in 2019 from Jason. The car will finally be paid up by October 2024. This car has never had an issue. Probably 5 flat tires in a 5 year span. I would definitely shop here again. I was in and out, even with poor credit. They work with you.

I can’t express how much better BMW of Ridgefield, CT,
I can’t express how much better BMW of Ridgefield, CT, was at every stage of my purchase compared to every other dealer I dealt with while searching for an i4. Every text message, phone call, test drive, and document signing was so clean, straightforward, and relaxed. It felt like I was working with actual humans, not just “salespeople”, which was unlike ANY other dealership I contacted. Even though they’re hours from my home, I’ll absolutely go to them first the next time I’m in the market for a BMW. Oh, and I ended up getting a pretty great price, too! Shoutout to Allan, Genesis, and Malachius for an awesome experience!
A fun and enjoyable ride!
Yes, it’s crazy powerful but you can definitely tame it to be a fully enjoyable ride for everyday use. I look forward to many years with my new X3M!

Sporty and functional
Perfect cargo size and no sacrifice in performance. I'm 6'2" and don't feel cramped. M40i engine and suspension make this a fun car to drive. Love the blue color!

Good experience for the most part. Come here ready to spend money! The staff was nice and pretty straight forward one thing I’d say could be improved is just the communication.
The second M version BMW to own.
Had X4M40I previously, which was a great vehicle, but this new X3M Competition has more interior space, better styling, and lightning performance. Wife and I have always enjoyed performance vehicles and this X3 delivers the fun.
