New and used 2026 BMW X5 xDrive40i for sale near Diamond Bar, CA

The team is always great and welcoming. 10 on 10 service! I feel very comfortable bringing my car here, and the team ensures I get all the work needed for my vehicle.

I appreciate how kind and helpful my sales person Jose Chichipa was. He really took his time listening to what I wanted and showed me several cars on the lot and online until I decided on the car I wanted. It took me several hours over the course of two days to finally come to a decision yet Jose was very patient and professional the entire time and made it an enjoyable experience from start to finish. I would without a doubt recommend him to anyone interested in buying a BMW.

Excellence isn?t just about delivering a premium product?it?s about the journey leading up to it. My recent purchase of an SUV from BMW of Buena Park exemplified that principle in every possible way. From the moment I arrived, I was met with a level of genuine courtesy and professionalism that immediately set the tone. The staff didn?t push?they listened. Every interaction felt personalized, thoughtful, and grounded in authentic respect for my needs. It was clear I wasn?t just another transaction on their sales sheet?I was treated like a long-term client from day one. The process was seamless. Communication was transparent, paperwork was handled with integrity, and there was never a moment where I felt rushed or misled. That alone earns high marks in my book, but the experience didn?t stop there. The SUV itself is everything one could hope for?refined, powerful, intuitive. But what impressed me most was the dealership?s attention to detail and commitment to delivering value beyond the vehicle. Every step of the process?selection, explanation, delivery?was handled with the kind of care that builds lasting trust. There?s a quiet confidence that BMW of Buena Park operates with. It?s not flashy or over-promised. It?s simply genuine, professional, and consistent. I left not only with an exceptional vehicle but with a deep sense of appreciation for the people who made it happen?and a dealership I now trust without hesitation. It?s rare to find an experience that blends enthusiasm, honesty, and excellence so effortlessly. BMW of Buena Park does it right?and earns my highest recommendation.

Adrian took care of me throughout the entire service process. Set me up with a loaner, kept me updated with my vehicles repair status and got me in and out when my vehicle was ready.

I was an out of area customer. Even at that it was a quick & easy purchase. Nothing more to say and certainly nothing negative to write.

My experience here was amazing! The staff were pleasant. Ron assisted me with my purchase and it went so smoothly I was shocked! I highly recommend this dealer.

Jorge at Long Beach BMW was very helpful and informative in us buying our BMW. He made our time matter and our overall experience a positive one!!

I highly recommend Collin. He made the buying process seamless. He was the best salesman I?ve come across in my search for a car. He was courteous, kind, understanding and passionate about his job. It was a refreshing change to the usual salesman. The process of all the paperwork was handled brilliantly by Branden.

Came in, they helped me really fast. They listened to my needs and they found a solution that worked for me. Paperwork was fast and professional, literally everyone here did a great job.
