Used BMW X3 for sale near Trumbull, CT under $899,990

I ordered an incoming car from BMW of Waterbury from Dennis. I can’t say enough positive things about how I was treated by Dennis. He guided me throughout the entire process and continues to keep me posted of the status of my car. He is a very professional ,trustworthy and pleasant person to work with. He is an asset to this dealership and look forward to working with him in the future!!

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.

I recently purchased a preowned BMW X5 from Dennis Smith at BMW of Waterbury. He went above and beyond to ensure that I was happy with my purchase. Hats off to him. A true professional.

Fully satisfied with the service rendered. Haley and the rest of the team went above and beyond to make things happen. Keep up the good work 😊

Excellent dealership. I worked with Phil and bought a Nissan Rogue. Phil is the best salesman I have worked with. He made the whole buying experience so easy and stress free. I’m so happy with my purchase. My entire experience was top notch. Thank you Joe and Marcelo also. You guys are great!!

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

Great car dealership! John helped me locate the Mercedes that I wanted with a premium 3 package. The car is exactly what I wanted at a very fair price. They also got me a very competitive car loan at a great rate! When I picked up the car it was beautifully detailed and although the car is a 2018 it looks like it came off the showroom floor and drives that way too

This vehicle was very fun to drive, it is comfortable and sporty, and the handling was excellent. Barely any issues, just overall a great driving experience.

Patrick is the MAN. Smart buy auto sales is lucky to have a colleague working with them. My daughter’s first official car purchase was exceptional. Patrick treated my daughter with such kindness and shared his knowledge and explained everything clearly. I’m one grateful mom to know that my daughter drove off their lot in her new car worry free. Thank you

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.

Excellent service. They also provided me with a loaner.

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.

Prompt and efficient service. My check engine light was on and the service department replaced a malfunctioning indicator at no cost to me.

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.

Best experience we had with car purchasing, found the car online, we drove 50 mins from NJ, Christopher made our experience remarkable. He was very detailed, fair and patient! Shawn from finance helped us in making informed decision about extended warranty. Over all very good experience with Mt. Kisko BMW. Highly Recommended.

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 !

This has been the easiest buying experience ever in my life. I live in Bloomfield, NJ. I saw a low mileage 2018 Honda CRV advertised from BMW of Greenwich on the internet. I called the dealership about the vehicle. I was instantly put on the the phone to Tom Forte. This man in his own words "Is old school". What a gentleman! I told him want I hoped to pay for the car and explained I didn't want drive all the way to Connecticut to haggle over price. Tom Forte immediately contacted his manager to see if we might have a meeting of the minds. Tom quickly emailed me a quote which was close to the price I was hoping for. I took a trip up to Connecticut. I took the car out for a test drive. Their was NO pressure at all. I knew immediately, I liked the vehicle. Tom got an appraisal done on my trade in a matter of minutes after the test drive. He next presented me with an out the door offer, that I thought was GREAT! But I promised myself I wanted to see another vehicle in White Plains. So I told Tom that. Tom did not try to dissuade me in any way. He told me to get back to him if I was interested in completing the deal at BMW of Greenwich. The Honda dealership in White Plains could learn a few things from the folks at BMW of Greenwich! They made me wait at ten minute to talk to me and then another at least a half hour before they could locate the car a wanted to see. The car smelled of old cigarette smoke, and it had other issues. Needless to say, I contacted Tom Forte immediately upon leaving that dealership. I have no regrets! Tom made me feel like a valued customer. On pick-up day, the car was bright and shining and ready to go. Tom offered me coffee and snacks while I was escorted to the finance officer's office. Again, no pressure and no wasting my time, but certainly a warm cordial atmosphere while finalizing all my paper work! Would I like to buy another car from this dealership???? You bet I would! Anytime!! I highly recommend Tom Forte and the staff at Greenwich. Thank-you all for making my buying experience, relaxing, easy, and fun! I love my Honda too! - Maybe next time I'll come back for a BMW!

5 stars for a 5 star overall experience. Alex is incredible to work with. He is kind, attentive and knowledgeable. This was my first time at this dealership and the transaction could not have been smoother. It was truly a pleasure. I am so grateful I got to work with Alex and I am loving my new car. Bravo Alex!

Great experience buying our 3rd BMW from BMW Greenwich. I highly recommend Patrick McHugh. It’s a pleasant experience from start to finish. Fair prices and a professional roll out from start to finish. These guys are pros!

I purchased a used car from Greenwich BMW and couldn’t be more pleased with the process. As an out of state buyer, I was concerned with the potential tax and DMV issues. My sales person was very professional and answered all my questions and explained the process thoroughly. Upon arrival, the car was in impeccable condition, as stated in the advertisement and they honored the trade in value discussed over the phone. The loan process was quick and there were no surprises! All in all the best car dealership I’ve had.

We were blown away by the experience. Tia and staff made this the most pleasant purchase we’ve encountered. Tia was so helpful and professional at all times, however she made this a fun, smooth and memorable purchase. We’ll see you all again in the near future.
