Used BMW X3 M for sale near Saint Louis, MO

Good honest salesman and manager. Giovani and Andre'. Great car at a fair price. No extra xx fees. Only what they told me when i called.

I’ve owned my 2021 BMW X3 M for a while now, and it’s honestly one of the most underrated performance SUVs BMW has ever built. The S58 engine is an absolute animal — smooth when you want it to be, but brutally fast the moment you put your foot down. It still blows my mind that something this practical can pull this hard. The handling is what really sets it apart. For an SUV, it feels planted and confidence-inspiring, especially in Sport Plus. Steering is sharp, body roll is minimal, and it genuinely feels closer to an M3 than an X3. Interior quality is exactly what you’d expect from BMW — comfortable, solid, and well thought out for daily driving. Maintenance-wise, staying on top of service is key with these cars, especially with how hard they’re meant to be driven. I’ve learned a lot about the platform and common service items just from owning it, and having a knowledgeable BMW specialist makes a big difference. I’ve come across helpful BMW-specific service info and ownership insights through https://www.bavarianautowerke.com , which has been useful for understanding long-term care and expectations. Overall, the X3 M is the perfect balance of performance, utility, and everyday comfort. If you want M-car excitement without giving up space or practicality, it’s hard to beat.

Steve was very helpful. He stayed late to help a friend buy a new car. Made process as nice as possible

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.

Jeremy Marx who handled the financing was excellent. He was very good at explaining every step and never put any pressure on me.

I've had my X3M40i for 1 year and love it. Absolutely no problems at all. Just had my 1 year oil change and the oil was still clean. I highly recommend this vehicle !

Just bought an amazing C63 and couldn’t be happier. The car is incredible and exactly what I was looking for. The salesperson made the whole process easy and smooth, answered all my questions, and didn’t pressure me at all. Great experience overall — highly recommend.

Own a 2020 x3m competition . Bought it brand new. Not one problem to date 4/16/2025 Just like any vehicle....stay up on your maintenance and oil changes , tire pressure etc. all good love this car!

Service is the best around and they always go above and beyond to help me out! Fidel, Nick and David Tyson are awesome! Highly recommend BMWCL for all of you BMW service needs.

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.

Felt very at ease shopping for the vehicle. There was no pressure and the sales person, Phyllis, as well as other staff were friendly and accommodating. A slightly longer vehicle orientation would be welcome as there is a lot to know about the X5.

Diego and Randy and Hasiel were excellent to work with. Clear explanations and helped to fit the purchases into a very hard budget number. Only star missing is due to the required LoJack and window etching, but they made the numbers work, which is the ultimate bottom line. Would def recommend them

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.

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.

Best Experience I have had purchasing an automobile. Salesmen was a young professional who knew the product inside and out and was quick to alert and educate me on all of the nuances of the car, an AMG SL-55. Price was far and the entire transaction was stressless. I highly recommend J& S and my salesmen Max.

I love the excellent customer service I received at Clovis Toyota. From the moment I arrived to my appointment, the staff was polite and professional. Thank you Paul!

Very good people 🙏🏻👌. They did excellent job respond timely manner Maybe hopefully I may get to work with them.

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!

Recently purchased and process was swift and handled well. Felt compelled to “try” other brands over the past several years. Some good and some bad but it’s the total process of car ownership that drew us back to BMW. BMW prett much outmatches most brands as far as driving dynamics. Most importantly the care and gratitude of service has helped us return to the brand. The team has done a great job to make it an easy decision to purchase again.

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!

Matt did a great job in expediting the transaction….seamless . Also, appreciated the follow up on how car is after we left. Thanks for the car!

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.

Very smooth transaction. Arrived at price over the phone. Drove the 3 hrs to Bendm viewed the car, they checked out my trade and I was on my way back to Portland in 2 hours.

Staff kept me informed about the vehicle I was interested, kept reaching out unfortunately could not go to look at the vehicle due to a family emergency.

This was our second day of looking at cars and nobody treated us better than Sewell Lexus. We came to buy a used Subaru Ascent; they had the car clean, ready and nearby for us to test drive. We got what we expected for our trade in and left in just a few hours very happy. I highly recommend Sewell Lexus of Dallas, they were great!

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!

I would like to thank Erick Martinez and Chase the finance manager for always taking quality care of me. I really trust what they say to me and feel like the best ever each time I drive off in a new purchase. I will always be your client. This makes my third purchase from BMW of Tampa Bay, it must be Great service for me to keep coming back. Thank you so much, I love my beautiful car. Yours truly Sheliajo
