New and used 2026 BMW M440 for sale near Diamond Bar, CA

Reaching out and expressing interest in purchasing a new car, they were very accommodating and provided clear communication, to include instant quotes. Once I purchased my car, it seemed as if the communication has lapsed unfortunately.

Over the years I've heard a great deal of the outstanding driving experience and fabulious features of the BMW cars. Now that I have purchased a 2026 M440X I understand their praise. The slogan " The Ultimate Driving Experience" is not just an advertising gimmick. I'm still learning the many, many cool features of my car even after the excellent tutorial by the Dealership and reading the manual. In short, I'm sold on Germain Engineered cars and am now part of the BMW family. Too bad US car manufacturers don't make this quality of car. My opinion, is that it the cost would be outside the reach of most Americans.

When I need to get my car serviced I wouldn't take my car anywhere else but BMW of Ontario. My advisor Sergio always makes sure everything is taken care of. He always makes me feel like I'm high priority.

Eric Li my service advisor went above and beyond expectations as he went to bat for me multiple times to keep repair costs down. I think he is the best

This dealer had great customer service from beginner to end. The salesperson was friendly, no pressure which I appreciated and if he did not know an answer he found it for us. The procurement part took awhile like expected but they worked with us until we were comfortable with the loan.

It was my pleasure to buy a car from Bmw of Monrovia. Monica Perez and the sales team made buying a vehicle, simple and straightforward.

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.

We had a great experience with Pacific BMW. The car we purchased was beautiful and we got a great deal for it. The only negative part of the purchase was the actual buying process. It took a little longer than we expected and maybe it could have been a bit more streamlined. But in the end, the car was worth the wait.

We met Sami Asadourian when we went to BMW New Century looking for an X3. We had initially looked at a loaner special to lease, and Sami took us for a test drive. After the test drive, we realized the car doesn’t have one of the options we absolutely wanted. Sami was very helpful in locating another vehicle that has all of the options we wanted. After a couple of hours of negotiation and finally came to an agreement on the terms, we went to look at the car – only to find out it doesn’t have something else we wanted. We were all tired and decided we should just go home. Sami told us he will find the car we both wanted, down to each options and packages. Boy did he come through! He called us the next day to let us know he found the car we wanted. To top it off, it’s an even better car – 2019, instead of 2018, and a better monthly payment! When we got to the dealer, the car was washed and ready to go. All we had to do was take care of paperwork. He made the process seamless, and made sure we wouldn't have to spend too much time there on our second day. All in all, we are very happy with our new car and very grateful for Sami’s dedication in finding us the perfect car. We would definitely go back to Sami for our future car needs, and we would highly recommend him to our family & friends, and to anyone shopping for a new BMW.

This dealership was honest and up front with me. I was interested in a truck. I sent a email about it, they responded very quickly and seemed interested in assisting. Before I got to the dealer the truck was sold. No problem with that. Someone got their first. What I liked is the dealer let me know before making a 80 mile drive the truck was gone. I recommend this place.

My experience at Long Beach BMW was excellent! Jorge and Andy were quick and efficient in getting the deal done. 10/10 customer service?highly recommend!

They give great service everytime without fail. My service advisor Sergio is the best there is. I can always count on him to let me know what's going on with my car and what I need to keep it running in tip top shape.

Great Service Adviser John Thasher, very knowledgeable and very professional.Makes visit seemless. Thx John

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

Buena Park BMW is my go to when I need my car serviced. Rigo, the service advisor was very attentive. He was able to provide additional recommendations for my next service, so I?m prepared for next time around. I highly recommend BMW of Buena Park, all staff is friendly, welcoming and most importantly they care about your concerns and your vehicle.

I bought a used car that was highly sought after, based on it having only 2k miles per year and it's price point. I worked with Ed, who went out of his way not only to reassure me that I had secured my spot as the buyer, but also provide me with photos and updates as the car went through the reconditioning and detailing process. Ed was extraordinarily responsive, answering my (many) texts within minutes! Ed demonstrated exceptional professionalism, caring and compassion. I would buy another car from him in a heartbeat.

I had been reviewing your cars on your website for about a month. I had favored a 2023 X2 on the site. I tracked it for about a month. When I finally had some time I decided to come test drive it. When I arrrived with my friend, we walked the lot looking at all the different cars. We were greeted by Alex Dimov while looking for cars. I told him that I was looking for a particular car and he pointed it out right away. He asked me if I wanted to test drive it? and away we went. While we were driving we had very pleasant conversation. He is extremely easy to talk to and he made me feel comfortable. Once we got back we decided to explore maybe purchasing the car. We sat down talked business, did a lil negotiating of price and a deal was made. I have to say Alex made the whole transaction pretty much painless. It felt more like a conversation than a negotiation. He knows how to talk to people and make them feel comfortable in what some might say a is a stressful situation. I didn?t feel any stress or being uncomfortable during the purchase process. Once a price was agreed upon Alex introduced me to the finance guy?. Sorry I forgot his name. He was also very easy to talk to and kept it stress free. While I was with him, Alex had the car detailed and fueled. When i finished with finance Alex walked me over to my new car handed me the key and took pictures for me. He was very helpful in explaining how to operate the car. Lots of bells and whistles I never used before. Alex was so patient teaching me. He actually help me set up the Apple CarPlay and a few other things. He let me know if I had any other questions or concerns I could call him for help. The next day he did text me to make sure I was ok and to see if I needed any assistance. I feel lucky and blessed he was my Salesman. Such a pleasant, stress free and almost fun experience because of Alex.

Shut out to Anthony Moore - my service advisor of my BMW X5 on Nov 11. He’s very professional and knowledgeable . Not much waiting.

Rudy is hands down the best BMW customer service representative we’ve ever worked with. We truly appreciate him and everything he does for us. Every single time we bring in any of our cars, Rudy goes above and beyond to make sure we’re taken care of from start to finish. He’s professional, knowledgeable, honest, and genuinely cares about his customers. It’s rare to find someone who consistently delivers this level of service, and we’re incredibly grateful to have him as our go-to person at BMW. We’re proud to work with Rudy and always know our vehicles are in great hands. Five stars isn’t enough—thank you, Rudy, for always taking such great care of us! Thanks The Cervantes Family

Highly recommend Service Advisor Bryan Ortiz at Crevier! I could drive to a closer dealership, but I’ll drive the extra miles for any service needs because of Bryan Ortiz
