New and used 2026 BMW 840 for sale near Algonquin, IL

it was just some presales questions and they were quick to reply and offered a lot of assistance.

I always have a great experience when visiting Bill Jacobs Bmw. Everyone working here is always very professional and kind such as Jacob my advisor.

The dealership contacted me and followed through on everything I asked and needed of them. Great overall experience.

Vel is a great sales guy. Very responsive and will work with the customer. We drove from MI with a trade in and they honored their offer. There were a couple minor things like steering wheel was more worn than we would have expected given the nice condition of the rest of the car. Small headliner plug interior for convertible top was missing. Other than that it was a smooth transaction.

Fast and easy. All staff was pleasant, well spoken and mannered. Made an out of state purchase with a few email and phone calls. Sales person Luke was excellent.

I throughly they were professional, low pressure, responsive and transparent. I went to several other dealerships and found them to be lacking in follow through and rude to my daughter. Kai’s was a breath of fresh air.

Bill Jacobs service is amazing, my advisor Mike A has been helping me for years and does a great job for me.

Huge shout out to Russ at Bill Jacobs BMW in Naperville. This was my second vehicle purchase from Bill Jacobs, and once again the experience was seamless from start to finish. Russ had everything prepared before I even walked in the door. The vehicle was ready, the numbers were clear, and the entire process was efficient and respectful of my time. The test drive confirmed everything, paperwork was handled quickly, and I was in and out without any pressure or unnecessary back and forth. Exactly how a premium car buying experience should feel. What stood out most was the professionalism and straightforward communication. No games. No surprises. Just a clean, well structured deal. I’ll absolutely continue purchasing from Bill Jacobs BMW in the future, and I highly recommend asking for Russ if you want a smooth, stress free experience.

Great service all around, service was attentive and complete, always kept I informed, I would recommend EJ

Jerry in service department really took great care of me. Alex in sales as well. 5 star experience every time I go to Fields BMW.

After being “in the hunt” and navigating disappointing experiences with at least seven different dealerships—including two other major BMW locations—I can confidently say that Bill Jacobs BMW is in a league of its own. I worked with Preston, along with sales managers Shaun and Gigi, and the entire team truly went above and beyond my expectations. Where other dealers were frustrating or opaque, this team was clear, transparent, and incredibly efficient. What stood out: Professionalism & Care: From the first negotiation to the final signature, I felt like a priority—not just another transaction. Patience: They took the time to walk through every detail of my deal without the typical high-pressure tactics. Seamless Process: The transition from negotiation to financing to vehicle setup was smooth and handled with impressive precision. Buying a car can be an exhausting process, but this team genuinely restored my faith in the experience. If you’re tired of the runaround at other dealerships, save yourself the headache and ask for Preston and the management team here. They are true professionals who actually care about their clients. And yes—the new BMW M340i is absolutely fantastic. Thank you again to the whole team.

Very easy to deal with and there were no hassles at all. I would recommend this dealership

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.
