New and used 2026 BMW X3 for sale near Ontario, CA

Visited to test drive through Costco Auto program. Monica was prompt in connecting and arranging a test drive. Since she was occupied with a customer, Olya assisted. She was very professional throughout the test drive and purchase of a 330i. Negotiated a fair deal and the following day Olya drove 30mins to our house to sync our phones with the car and demonstrate the digital functions of the car! Great experience from beginning to end

So grateful for Monica—she really cared, understood my needs, and helped me get the perfect BMW.

I had a great experience with this dealership. The staff was professional, friendly, and very patient throughout the entire process. They answered all my questions clearly and made everything smooth and stress-free. The car was exactly as described, and the whole purchase process was transparent and efficient. I truly appreciate their excellent customer service and would highly recommend this dealership to anyone looking for a reliable vehicle.

I bought my BMW X5 from BMW Monrovia. Monica Perez was my sales person. She did an amazing job finding the right car I needed. She even found and added all the accessories and rims I wanted. If you’re looking for a car see Monica. She will make it happen and you will be highly satisfied with the result on the car you want!

I had an excellent experience at BMW of Monrovia and wanted to take a moment to recognize the team that helped make everything happen. I recently traded in my previous M4 competition and purchased a new double Individual M4 Competition xDrive, and the entire process was smooth, professional, and enjoyable from start to finish. My sales advisor, Bassel, was fantastic to work with. He was honest, straightforward, and extremely knowledgeable. There was never any pressure, and he made sure all of my questions were answered while helping guide me through the process in a very transparent way. Paul, the General Sales Manager, personally oversaw the transaction and made sure everything went smoothly. It was clear he truly cares about the customer experience and about doing things the right way. Jeff from the used car department was also great to work with. He provided a very fair offer on my previous M4 and was friendly, accommodating, and easy to work with throughout the appraisal process. Ryan in the finance department was incredibly helpful as well. Both he and Bassel stayed late to make sure everything was completed properly so I could drive home in my new car that same day. Their willingness to go the extra mile really meant a lot. Overall, this was one of the best dealership experiences I’ve had. The team was professional, respectful, and genuinely focused on helping me achieve my goal. I’m extremely happy with my new M4 and very grateful to everyone at BMW of Monrovia who helped make it happen. Highly recommend this dealership and this team if you’re looking for a great BMW buying experience.

Dealership service can sometimes feel like rolling the dice. That has not been my experience here, largely because of Adrian Kim. This was not my first visit, and of course, another random issue decided to pop up. Cars have a sense of timing like that. I texted Adrian, and as usual, he handled it calmly and thoroughly. No back and forth, no confusion, just clear updates and actual follow through. He pays attention to the small details, which honestly is what separates good from great. The whole process feels organized and respectful of your time. The loaner was a brand new 2026 model, spotless and ready to go. Almost made me forget why I was there in the first place. Service visits are never something you look forward to, but working with Adrian makes it surprisingly painless. If you are coming to BMW Buena Park, do yourself a favor and ask for him. He makes owning a BMW feel the way it probably should feel.

Adrian made the effort to get my car done. We ran into a few snags however Adrian made everything good again. He goes above and beyond.

I had a great experience working with Adrian at BMW of Buena Park. He was professional, knowledgeable, and took the time to answer all my questions. The whole process was smooth and easy. I?ll absolutely be recommending him to friends and family!

They were expecting my car and took it in quickly. People there were friendly and helpful. They did the requested work and had the car back to me timely.
