Used BMW X3 for sale near Smithtown, NY under $799,942

I visited mainly to compare a couple of models. The staff was helpful in providing information and letting me test drive without feeling rushed. Didn't buy on the spot, but it was a positive and informative visit that will definitely bring me back when I'm ready.

It's all about the B58 in the M40i. I dinged it one star on comfort because this little SUV rides quite "sporty" even in Comfort mode. I absolutely love this about the car, but I could see how some would feel this is too harsh as it is not a luxurious, cushy ride. But tuck this little beast into a fast corner and it's just...wow! This little German SUV is a sleeper. While the X3M is very nice, the M40i is the perfect balance in my opinion. BMW has really stepped up their game in the X3.

Great car love bmw very reliable never had any mechanical problems great in the deep snow Excellent acceleration Handles and drives like a sport score

This vehicle has has taken my wife and me cross-country, as well as several other long distance trips, with a sum total of only one flat tire and no other mechanical, nor electrical issues at all! Any repairs have been moderate and frankly expected given the high number of miles (150,000 so far) on it. I expect to keep it for another year and a half.

I have purchased two vehicles from Beverly Hills Auto Group and have been treated with World Class service on each occasion. From the quality of the vehicles to the efficiency and friendliness of the staff you will not have a better buying experience anywhere. I highly recommend this business to anyone looking to purchase quality used car.

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

its really a amazing when i sit on seat then i realize like a king so i will recomend to everyone which they want to live luxurious life or resemble like a king

Love it. Car is comfy, quick and the wonderful B58 Twin-Scroll Turbo I6 makes all the right noises! Awesome daily driver. Period! Interior has all of the amenities you could ever ask for. Ride is luxury-oriented but also can grip & RIP through the corners, almost as well as any sports sedan out there pretty much.

Straight forward and professional. Didn’t make the purchase, but very satisfied with their communication.

amazing experience from start to finish! Phil called immediately and his office was communicative with all the paperwork, etc. I also appreciated that there was no pressure and he is very knowledgeable.

My husband and I just got a vehicle from Dan and Anthony. They went above and beyond to get something that we was satisfied and we are grateful & very very happy with the sale of the Nissan Versa. Car runs like we just bought it NEW CAR right off the lot. Dan did an excellent job and people that we know that got cars from him were all very happy Especially US.. WANT TO THANK DAN AND ANTHONY VERY MUCH.. We would recommend Best Buy Auto Stop to any and everyone for any vehicle. They go above and beyond for their customers. Thanks again Dan and Anthony.

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 have not bought a used car in 22 years as I have never had luck with older cars. I was driving by M&A and saw a vehicle that peaked my interest. I went in expecting the worst and instead I got a great experience. Even better than leasing a new car. Keeya was upfront and fair. He even helped me arrange for the Jeep to get inspected at my local mechanic. Before I lease another vehicle, I will be checking out M&A.....

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.

What a great experience all arround very professional not your typical pushy car salesman I highly recommend them and would use them again in the future.

I cannot believe that BMW put a 4 cylinder with turbo in an X3. It is the single problem I have with my car. otherwise it is perfect. The 6 cylinder in my 2005 was Awesome!!!!! BMW stands for Performance, GIVE IT.

European auto company i’m very happy with the treatment that I received from Matt and the sales staff they made me feel at ease I would recommend European auto company to anybody who’s interested in buying a nice car

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 !

Matthew made the process so easy. I usually hate car shopping, but he actually made it enjoyable. No pushy sales tactics, just helpful, honest advice. I love my new ride—thank you Auto Lux!

I submitted an internet inquiry overnight, and as soon as they opened, Ephraim Senteio promptly reached out to me. I was very upfront about my busy schedule running multiple businesses and mentioned that I didn’t have time for window shopping. Ephraim completely respected that and connected me with Client Advisor Sam Al-Hajjaj, who was absolutely phenomenal. Sam worked efficiently to provide great pricing and handled my trade-in with care, making the entire process seamless. Jake DeMattia from the Genius Center was incredibly helpful, ensuring I had all the information I needed about my new car. Danny Rodriguez in finance was both friendly and efficient, making the final steps of the purchase smooth and stress-free. I purchased an X5, and I couldn’t be happier. 5 stars! My only feedback, as someone who frequently purchases high-end vehicles (Range Rover, Aston Martin, Acura, etc.), is that the dealership can get very busy and you can tell the staff was overwhelm, I think some technology could help them because people would get lost in the waiting room like we did :). This is understandable, especially on a weekend and the last day of the month—partly my timing. Overall, I look forward to building a long-term relationship with this amazing team. After almost 10 years, I’m thrilled to have a BMW back in my garage. Highly recommended!

I bought my first BMW in 2014. A new 640XI convertible... I have purchased many new vehicles including 5 Lexus 4LS models and 1 Sports coupe. The BMW was without a doubt the best. Now with regard to customer service as well as service departments (which is almost as important as the car model I select) Rallye BMW was without a doubt the best in both categories. So now that my BMW is eleven years old my wife and I decided it was time to look for a new car. There wasn't much to think about so we returned to my Rallye BMW dealership in Westbury and go for a test drive. Immediately after that test drive we returned to the dealer and negotiated the purchase of a new 2026 8XI convertible. We met with our service advisor, Frank Trotta, who has been taking great care of the 2014 model and gave him the good news: Frank we are buying a new BMW. Mr. Fitzgerald, When you and Mrs. Fitzgerald can come in I will introduce you to my friend Angelo a sales Representative...We met Angelo, another great representative from Rallye BMW and now we are waiting for delivery. I highly recommend If you are looking to buy a new or used BMW you give Rallye BMW, located in Westbury NY a visit.

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.

Michael M is the real deal. Very professional and straight talking. My experience working with him was very positive. Lisa H

I have used the 2019 BMW X3 for over a year now, as my third BMW, the other two being the 3 series sedan, with just one problem; Fuel pump failure, though due to my negligence. I now understand that the BMW cannot be operated without sufficient Fuel.

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.

I just picked up my 2024 540 M and it was an unbelievable excellent experience! This is my 7th Vehicle From BMW of Mamaroneck and Brian S. & Nicholas N. Treat me like family, honest, full disclosure, professional, and satisfy every need. I have full faith and trust in the people who have serviced me over the past 12 years. This is why I am a repeat customer and would recommend to anyone to meet these two great professionals you would be in the best of hands, they will work very best to satisfy your purchase needs

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

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.
