New and used 2026 BMW M340 for sale near Bolingbrook, IL

Naeem was great to work with. He was able to read the room and get right into it without the unpleasant ?sales? verbiage and time wasting drama. Kudos Naeem!

Alan S. was upfront / transparent on pricing and patient helping us figure out what we need, bouncing between models and trims. Appreciated the follow-up after buying to see how things were going and if we had any questions. Very helpful w/r/t getting the most out of the vehicles functionality after driving it for a week.

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

Easy buying experience. They were very professional and the whole purchasing process was with one person.

Another great experience at Joe Perillo BMW with Michael Fezatte. He made the whole process very simple and turned around our new car search from first contact to leaving showroom with the chosen vehicle (complete with custom spec) in less than 7 days. He understood what we were looking for and delivered a no nonsense, enjoyable buying experience. We will be back again.

Staff professional. I plan to come in when westmont calls to go over my car , it was a loaner and had little damage. Then I will go over the tech again with Jennifer.

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

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!

Garrett Goldstein did an excellent job. Really appreciate his help. Start to finish he got it done

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.
