Used BMW X3 for sale near Old Greenwich, CT

Everything was great from beginning to end. Antonio was great. He was very Helpful, and nut pushy. Everyone I encountered at the dealership was friendly and helpful.

I had a wonderful experience purchasing my new Honda HR-V 2026, and a big part of that was thanks to Donald. From the very beginning, he was incredibly open, honest, and respectful of my decision-making process. He was never pushy, which made the entire experience stress-free and enjoyable. Donald took the time to understand my needs, budget, and expectations, and allowed me to take full responsibility for my choice while offering guidance only when I needed it. He was transparent about pricing and genuinely focused on helping me find the right vehicle rather than just making a sale. I would also like to recognize his manager, Alex, who was very helpful and supportive throughout the process. Together, they made sure everything went smoothly and that I felt confident and comfortable with my purchase. I truly appreciate their professionalism, patience, and customer-first approach. Thanks to Donald and Alex, I had an excellent experience and couldn’t be happier with my new vehicle. I highly recommend working with them if you’re looking for a smooth, honest, and pressure-free car-buying experience.

I love this car I bought it for my wife for her Birthday and she just loves it. The ride is great and all the extras it has it perfect

Salesman assigned to me was Billy Talla . Great knowledge & no pressure , test drove vehicles , settled on used 2023 X4 . Price was perfect for budget paid upfront no financing .Did not care for the finance department additional sales attempts for additional warranties & pre payments . Did not make sense for such a great brand , to me personally. Thank’s .

Only have been driving the car for a week, but it is clearly the best SUV I have experienced. My wife drives the Mercedes 300 - a fine car as well, but I have always preferred BMY engine performance and handling. The X3 is simply a pleasure to drive.

I don’t even know where to start, but this dealership and especially Patrick Laroque made my experience feel both luxurious and genuinely welcoming. This isn’t one of those dealerships that tries to push you in just any direction; they truly work for you and do their best to get exactly what you want while staying as close to your budget as possible. I purchased a 2023 BMW X4 and got the exact exterior and interior I wanted, seamlessly and all thanks to Patrick and the amazing team here, just in time for my 30th birthday. I’m incredibly grateful and can’t thank them enough. I’ve been driving my car for three months now and love it more every single day. Thank you again, and God bless you all!

This was by far my best car buying experience. Silvano (salesperson) was helpful, informative, and respectful. The paperwork and financial part was super easy. Very excited about my first BMW!

Our salesman, Raheem Moncrieffe, was outstanding. Friendly, clear and listened Carefully to us. I’ve bought many cars over my long lifetime, but he’s the best salesman I’ve ever had.

I absolutely love this car. Sleek design, very sharp looking. Drives like a dream. It takes a bit to learn where controls are for dash but, once you got it down, its easy.

Great experience and chemistry Joseph Etcheto was just flat out fantastic He made sure the car I wanted was available and worked on my time to make sure I was happy with this decision

BMW X3 an excellent car. I like the performance and enjoy using this luxurious car.🚘 I very much like having all the safety features.I appreciate BMW service.

Wow! What a smooth and effortless experience!! I have to give a special shout out to Miguel, who helped my wife and myself buy an amazing used SUV - a beautiful Nissan Rogue full option for a great deal with affordable payment options. He was such an angel. Thank you Miguel. Thank you Magic Auto Sales. You are the best ❤️‍🔥🙏🏽 I recommend this used car dealership for anyone who doesn't want to get ripped off by preying dealers.

I love the car and at the same time I can't help to hate it. What I love about the car would be the luxurious interior, comfortable and quiet cabin, smooth ride, ease of access, and a few extra features that were put in as an add-on. What I don't like about this car would be the poor fuel economy for the 30i model, especially when compared to the B-58 engine. Apple carplay connection issues, no option for remote start unless I want to void warranty, and no option for the iDrive Recorder App. Exterior Styling - 8.5/10 Interior Styling - 9/10 Comfort - 9.5/10 Cargo space - 8.5/10 Driving smoothness - 9.5/10 Horsepower - 7/10 Fuel Economy - 3/10 It's been an overall fun car to get around in. It's easy to get in and out of, smooth on bumpy roads, and it is quiet. The fact that only 2022 models and newer offer remote start and iDrive recorder is a big disappointment. But I think my biggest disappointment would be the fuel economy. As I had the B-58 in the past and averaged out 11.5L/100km and in this X3 am averaging 13.5/100km which was worse than my pick up truck. I might not keep this car for long-term just because of how poor the fuel economy is.

Great experience buying a used gx460. Isaiah was great to work with and even took care of me post sale.

Our salesman, Jonathan is a true professional. The dealership made this a painful experience. Never going back. The only reason we put up with 2 days of getting jerked around was because they were the nearest dealership that had the vehicle we wanted in stock. We'll never return.

Very Quick and smooth process. Sale agent victor was really nice. Would definitely do business with them again! Thank you again!

This is my 2nd BMW after keeping my previous 528 for over a dozen years ! Still going strong but had to change. After test driving a few, came back to BMW... Its like Apple, once you get an iPhone, it is hard to switch ! Bought a CPO, which gives us more time. Nice car. Good power. Have to constantly check the speedometer to ensure we stay within limits ! So silent and smooth... Love it !

My check engine light came on and they had the part in stock so I was able to have the issue rectified immediately. Also had an oil change & tire rotation done while I was there. The technician kept my car nice and clean, and Courtney was great explaining everything to me. Great service!

I am new to BMW and so far I am loving it, especially the way it handles the road and the overall comfort of the car

Worked with Jon! He answered all my questions and made the whole process very efficient!

I have had three BMWs, all with great reliability and high satisfaction, but this is my first BMW SUV. After 5 weeks of ownership, my 2024 X3 is on its way to becoming my all-time favorite. The handling is great, the safety features superb, and the comfort and luxury appearance have surpassed my expectations. We are so happy with this car that my husband is talking about getting one for himself, and he is an Audi and LandRover fan. BMW, thank you for your continued dedication to quality and reliability.

Awesome- Jaren’s the man and Jonathan’s great! Wonderful service, superior snacks… 2 enthusiastic thumbs up!

I love that BMW makes a mid size suv that is part electric now. We purchased the x3 edrive. I do mostly local driving during the week so only need to fill up with gas once a month to every six weeks. Excellent car!

Excellent dealership and Peter is the best. Purchased a great car with no hassles. I had a positive experience and would highly recommend them. They take great pride in their work. Thank you Peter!!

Our 2016 works flawlessly! We are so pleased we just purchased a very low mileage one with $15,000 in options which should make this one even more pleasurable,

I've had the 2025 X3 30 now for 5 months and it is great! It replaces our 2022 X3 that was recently totaled and both passenger walked away with just bruises so it is a safe car! This is one reason I purchased another X3. Big difference on the interior panel than the 2022 as everything has gone to touch screen for all controls which I not real fond about, even the owners manual is on the touchscreen software, The twin turbo gives plenty of power and the gas milage has improved from the older model. The gears change smoothly and the ride is also smooth. You now get a spare tire since BMW did away with the run flat tires which I hated as they did not wear great. The accessories offered in their package covers everything you want in an auto. I don't understand why the rear exhaust are hidden though as I like the chrome exhaust on my old 2022. This year the 3 was redesigned and it is slightly bigger.

Jeremy was fantastic to work with, transparent and committed to providing all the information I needed to make an informed decision. My experience purchasing a Mercedes-Benz C-Class C 300 at CPM was stress-free. If you're looking for a dealership that prioritizes customer satisfaction, I highly recommend CPM.

It has been a pleasure working alongside Carlos at stream auto. He and his team made it an easy smooth transition for me to leave there with a great car and a smile on my face thanks again team five stars to Carlos

Great place great people and kemo was a great help thank you for the great truck

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny
