Used BMW M850 for sale near West Chicago, IL

Adulfo at Acura of Westmont delivered outstanding customer service from start to finish. He was professional, patient, and incredibly knowledgeable. Every one of our questions was answered clearly, and he took the time to walk us through all of the technology and features in our new 2026 Acura MDX S so we left fully confident using everything. His attention to detail and genuine care made the entire experience smooth and enjoyable. In addition, the entire staff at Acura of Westmont provided first-class service. This was truly the best dealership experience we’ve had, and I will only buy from Acura of Westmont in the future. I highly recommend working with Adulfo and the team at Acura of Westmont.

I have driven many BMW’s but this one surpasses them. Not only does it have an amazing look but the feel and sound of a V8 is no comparison. I can leave it in comfort mode and relax or put in Sport and everything changes. I hope BMW leaves this one alone along with the M5 and not make into the electric garbage with these horrible grills.

Knowledgeable representative such as Jacob Murrar does an accommodating and tailoring job to my need

My experience with Sunset Auto was outstanding. They have a great selection of used cars, all in excellent condition. The sales team was friendly, honest, and very helpful without being pushy. They worked with me to find a car that fit both my needs and my budget. The paperwork process was smooth and quick. Overall, a very professional dealership that truly values customer satisfaction

It is amazing the difference 5 years can make. Traded a 2014 BMW 640i xDrive in for a 2019 BMW M850i xDrive. It is a beast! Handles great, very solid and I like the extra hp and features.

If you’re on a market for an ultimate driving machine. BMW of Elmhurst in Illinois is the ultimate dealer to get that machine. Michal is THE guy to see.

Happy that I purchased at this dealership rather than others in town. Turned out to be better deal and better car!

So fast and good looking; what more you want? Traded a Lexus LC 500, smartest move I've made. Love this car and hope to keep it a while.

I bought a 2011 VW Routan from Auto Gallery. Steve went above and beyond to make my car buying experience painless and easy. Great guys to work with. Will recommend to friends and family.

Justin always goes above and beyond. He pays attention to detail and I recommend him for future services!

Let me start off by saying JOHN (in service) is the real deal. He is the only reason I would come back to BMW & Elmhurst. Every encounter I had at this dealership he made it feel like my car was fresh off the showroom floor. His professionalism & attitude was great even when mine may not have been. Once again when I buy my next BMW and it will be at Elmhurst BMW, it will be because of John and sorry salesman I’m dealing with John on that purchase even if he is in service!!!!!!!!

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

The 2019 BMW M850i truly Is the ''gentleman's racer'', power to spare and refined interior make this BMW an ultimate driving machine. I've owned many BMWs, all were superb vehicles. This one, however, is the ultimate. I could put on a suit and dine out to an exclusive restaurant or put on a track suit and head to the track. I have the ''first edition'' with the special ''frozen Barcelona blue metallic'' paint and loaded with options...she is a very special vehicle.

I can’t say enough about the outstanding service at BMW of Barrington, especially thanks to Justin in the service department. He always goes above and beyond to take care of us. Justin is professional, responsive, and truly committed to making sure everything is handled quickly and correctly. No matter the situation, I know I can count on him to provide updates, answer questions, and ensure the work is done right the first time. It’s rare to find someone so dedicated to their customers, and Justin has made every experience stress-free and enjoyable. Thank you, BMW of Barrington, and especially Justin, for always delivering such an exceptional level of care and service!

I had owned a used BMW650i for 10 years and love the car for the look, size, performance and value. I decided to finally upgrade to a new 2023 BMW 850i. The car is incredible. The Horsepower is outstanding and the car drives like a machine. It has power, handling, and is sporty but you still feel like you have a full car you are driving.

Went in this morning for a maintenance check up on my truck outstanding service as usual no complaints

Just wanted to mention that I had a great experience buying my F-Pace from Patrick Jaguar of Naperville. Dale was just fantastic and went above and beyond helping me during the the whole buying process. The rest of the team (Finance & GM) was also excellent in their interactions with me. I initially chose Patrick Jaguar because they were one of only 2 Jaguar dealerships in the area that were not marking up their vehicles over MSRP, specially the hard to get ones like the F-Pace SVR which I bought. I've only needed to use their service department for a minor cosmetic issue that was sorted out in one day. Great job all around.

Owner of the company reached out to me and take care off all issues even it was after work hours. Good customer service.

Lots of power and comfort at the same time. Beautiful interior, very sharp looking exterior. BMW m850 is fun to drive! In Comfort mode, the M850i is soft and virtually silent but when it is to change in Sport Mode, it becomes a Beast!

Had a fantastic experience with Motor Cars of Chicago, Seraj “Raj” Abughoush was amazing to work with. He was attentive from start to finish. I am an out of town buyer and Raj worked with me to make sure I was satisfied before and after purchase. He followed up timely and walked the vehicle with me via FaceTime twice. He took me on a drive via FaceTime and even found a chip in the window and had it fixed before delivery. I will definitely buy another vehicle from Motor Cars of Chicago, they have a customer for life. The manager was also highly engaged And customer focused. I highly recommended and customer friendly. Thanks Raj and team.

Incredible style, luxury, performance, comfort, and tech too. Took the 6 series and redesigned every annoyance and inconvenience. Totally successful effort. Will probably depreciate quickly, but great value at any price!

Great service, fantastic service advisor, and a wonderful dealership! Jacob is a pleasure to work with.

I recently had the pleasure of working with Chris when purchasing my new vehicle, and I couldn’t be more satisfied with the experience
