The distinctiveness of a Mercedes-Benz vehicle begins with the quality of its Mercedes-Benz parts and accessories. Every component is artfully designed and promises superior performance, reliability, and longevity. Aftermarket parts won’t do your Mercedes-Benz justice; they simply aren’t strong enough to accommodate its advanced engine, transmission, brake system, etc. for long periods. They also don’t offer the same level of fit of the genuine parts you can find at our Mercedes-Benz parts center, which have been fabricated to precisely fit your vehicle instead of appeal to mass-market options. That’s why we recommend nothing but OEM parts to our customers for all their services, repairs, and enhancements!
Perhaps best of all, each part in our inventory is backed by a Parts Limited Warranty, doubling the peace of mind you can only get from buying Mercedes-Benz original parts. The Mercedes-Benz Parts Limited Warranty includes the protections of:

Mercedes-Benz of Ontario has been providing high quality customer experience from the very beginning. This time I went in for a malfunction on the auto-lock of one of the doors. The service rep Naeil did an excellent job documenting the issue, explaining the issue to the mechanic, and resolving the issue by replacing one of the actuators on the door. I definitely would recommend this dealership to anyone who wants a Mercedes.
Purchasing was made very simple and treated like a VIP! Very nice people working there and it was a pleasure doing business with them. The entire process was seamless.
The reason I continue to use Merecedes of Ontario is their customer support
I had been in line on a very hot day at the car wash awaiting my turn when a yellow light on the dashboard came on. It was late when my car wash was completed, but I took my car into the MBZ dealership in Ontario, CA where I had purchased and maintained my car. I was hoping it wasn't anything very serious, so, I didn't have an appointment. I went in after a doctor's appointment the very next day. I waited for my service person to come back from lunch. He tok my car in for ...
Abel Vargas was my seller and was very polite and professional. He did a good job answering any and all questions. I would recommend him to a friend.
Danika and the entire service team took excellent care of me. I was worried for nothing. The whole process was painless, and that same VIP treatment we got in sales was the same in service.
The team overall very patient and easy to work with.
