New and used 2025 Mercedes-Benz GLS 450 for sale near Rosemead, CA

The VIP new car buying experience I received at Fletcher Jones Mercedes of Ontario was one I will never forget! Having recently bought my brand new car directly from the dealership's General Manager, I had the privilege of receiving the VIP treatment from start to finish rooted in a true "collaborative effort." Teamwork made the dream work whereby the GM, Mr. Ted Moreno, lead his sales team with a hands-on approach to personalizing my purchase designing and ordering my dream car right alongside me! Each player on the sales team were highly professional, attentive, and experts in their respective roles that made the purchase of my custom built GLC Couple a joy and changed my car buying experience in such a way that I will continue to purchase and refer others to this BUY MERCEDES! Thanks to GM Ted Moreno, Addi Mimi, Ken Lau, Jonathan Graham, Emad Dagher and finance agent Shami Ramirez for and EXCELLENT Team Effort that speaks volumes about why I HIGHLY RECOMMEND this dealership and made me an extremely satisfied customer!

I never write reviews…. BUT!!! A HUGE thanks to salesman JEFF! We appreciated his professionalism and passion to help us find our new car. Even after buying ours, he was so kind and quick to answer any of our questions. We are definitely recommending Jeff to our friends and families!

Very professional sales people! They are the best .. I highly recommend them! I will not use any other dealers in the future. They are professional, fair, polite, and provide through information

recently visited Mercedes-Benz and had the pleasure of working with Mr. Jeff Tarin regarding the end of my lease end. I came in with a few preferences, which was to leaver MB & purchase a car with another Brand. I was uncertain about the most financially responsible path—whether to end my lease, purchase my current vehicle, or explore a new one. Jeff was incredibly mindful, honest, resourceful, and supportive throughout the entire process. His charismatic and empathetic approach immediately put me at ease. He took the time to thoroughly educate me on all available options, including the financial implications of each, while paying close attention to both my needs and my financial comfort. Although I ultimately decided to purchase a new vehicle, Jeff ensured that I felt confident, informed, and genuinely happy with my decision. His professionalism and care made a lasting impression, and I’m truly grateful for the time and attention he dedicated to assisting me. Thanks to Jeff’s exceptional service, I remain a proud and loyal Mercedes-Benz customer since 2017, and I look forward to returning to him for all future needs—both for myself and for my family and friends.

Came to WI Simonson after buying my last Mercedes from another Mercedes retailer. I?m so happy we came to WI Simonson and met our salesperson John. John was amazing; he was patient, kind, and very attentive. He made our experience very easy. We will definitely be back to WI Simonson and work with John again to get into our next Mercedes.

Natalie was awesome. Professional and friendly. Service and brake pads. Suggested only front brake pads were necessary. And tire rotation. Car was clean and ready early for pickup. Have been a customer for 20 plus years.

employees were very respectful and caring. they truly payed attention to what I wanted and gave me the best deal! they made sure I was happy with what I was getting.

It was a kind and professional service. I went to four dealers, I chose this place. I was able to choose a good car, and I am happy and happy.

Very friendly and professional staff. Will recommend to my friends for sure.

AutoNation proved to be consummate professions, living up to the recommendation to go there. They know their business and have amazing inventory. I would recommend them.

Update to a previous experience Today I took my car back to Glendal Cal Star My issue was resolved at no charge. I’m happy it was resolved and my car was repaired. Thank you

Bought eqs 580 our sales consultant was Tyler Kim and Billy in finance! Great guys great dealership.. smooth transaction totally recommend with 5 stars ?? plus!!!

The salesperson, Dorsa, was very helpful in choosing the right car for me. The process for final sale was handled smoothly by Tom. After the purchase, when a problem occurred, Babak in the service department organized the transaction swiftly and handed me the key to a loaner vehicle. The technicians in the back shop were spot on with diagnosis and correcting the issue in a timely manner. A Bavo Zulu (high praise) to all.

Great service, great guys and girl. was able to get a decent deal so far happy we’ll see.

Good service on the my lease purchase last month it was really easy process with the help a salesperson only took us around 2 hours waiting all paperwork.
