New and used 2025 Mercedes-Benz G-Class SUVs for sale near Placentia, CA

Everyone was amazing at Mercedes Benz of Ontario. Great customer service. Diana was my point of contact and she was very helpful and insightful. Will definitely return here for my future services.

Frank was super kind and took care of everything I was worried about with my car. He even found a broken front hook I didn?t notice. I left feeling totally reassured.

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

I had the privilege of working with Cristian when I purchased a beautiful mercedes benz recently. His professionalism and enthusiasm in helping me find the perfect car made the entire process easy and smooth. I would and already have, recommended him to friends & colleagues.

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

Just purchased my very first car and everyone over at Walter’s Mercedes was incredibly kind and helpful during the entire process! Big thanks to Alfonso Hernandez who was extremely friendly!! He really made the experience significantly better :) Thanks to the management there as well, esp Hae Lee who was also very helpful and nice! Will definitely recommend this dealership to anyone I know that’s looking for a great deal on a Benz!

I had a great experience buying my car at MB of Riverside. Liliana was very professional, knowledgeable, and nice and easy to talk to person. Sales manager Rob and finance manager Justin were very helpful and accommodating!!! Overall, I have a great experience buying my new car!!! Thank you.

We recently acquired a 2025 MB 450 GLEe from Walter’s with the help of Christian Aparicio. We our longtime MB owners so it’s a high bar with us but Christian exceeded all expectations. We couldn’t be happier and will certainly contact him the next time we need a MB. Thank you Christian!

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

Came in with family to return their lease and help them with the process. To be clear, we had an absolutely fantastic experience here. Let?s start with some history and establish the historically bad here for context: We came in for a lease return following a pretty poor experience with our first gen GLB. It was riddled with small electronics and misc issues within the first 100 miles. No that?s not a typo, borderline lemon it was that bad. We barely drove it 100 ish miles and already had noises and what might as well been a Christmas tree on the dash. However because these issues, and there were many, were small and not catastrophically bad in terms of safety and driveability, there was only so much we could do (or wanted to waste time doing). All of the issues were either addressed after multiple visits or simply not addressed at all after being given a half baked reason. We were literally told a loud squeaking noise on cold start and one that came back longer drives were ?characteristic? of the vehicle because they ?started a few other GLB?s on the lot and it made the same noise?. I?ll let the readers process that (it was fixed TWO years later btw). A real shame at the end of the day, but let?s chalk it up to bad luck and 1st gen issues (production location of the GLB aside). To be clear, my family and I have been customers of this dealership for over 10 years now and have always had good experiences up until the GLB, just wanted to highlight this experience after not having very many redeeming factors up until we met Isabelle. Now the good, and I cannot stress this part enough in my thanks: I don?t often write reviews, least of all for dealerships, but considering what a fantastic experience we had at Mercedes-Benz Arcadia recently, I really felt compelled to do so. After a number of not so great experiences during our GLB ownership, something we shared upon sitting down, Isabelle was quick to acknowledge it and immediately took the steps to help us get into what we wanted. She not only took the time to get to know both of individually, but also made it personable and more importantly, organic. We all know what these conversations are for, but to have it done on a way where it wasn?t forced and life experiences are shared goes a long way. All of this to say, it felt like less of a forced or rush transaction, and more of a conversation first. Something you?d be hard pressed to find in sales now, especially in so automotive sales in any capacity. Isabelle made sure we were able to look at any vehicle we wanted, even if it was parked in a dark corner of the cosmos. She went and grabbed each vehicle and pulled it right up for us to take a look at, even if it was the same spec, same color. She made sure we were sure of what we wanted before discussing anything else and really took the time to do it. She also fought for the numbers we had in mind and did everything she could to make it happen vs the ol? wait and bait approach. Isabelle was an absolute 11/10 from start to finish. She was patient, understanding, detailed, and very attentive to our needs. A rare find in the automotive sales let alone auto service industry. If I owned or managed this dealership in any capacity, I would fight to retain this woman and promote her at all costs. We will definitely be coming back to Mercedes-Benz of Arcadia for another vehicle and will certainly refer people to this dealership again. Many thanks to Isabelle W. for her patience and generosity. Special thanks to Finance Manager Billy Kwan as well for the very quick and efficient paperwork process. Your kindness and generosity does not go unnoticed. To the management at Mercedes-Benz Arcadia, if you ever stumble upon this or catch wind of it, please do give Isabelle and Billy our many thanks. They deserve recognition for their exemplary service.

Wow this is hands down the best dealership i went to. Usually I dread the finance part but John Hong my finance manager was a star amongst Stars! I Definitley will let everyone know about Calstar Mercedes led by Armen and company!

Professional and effective service especially while my service manager, Sonia, happened to be at lunch. Frank Perri stepped in to take care of my needs with a helpful and effective manner to take care of my needs even though he was very busy at the time - impressive!

Klee Gordon was exceptional , respectful , has a great personality and did the best to accommodate my needs. I highly recommend recommend Klee too help purchase your next vehicle.

Easily the best car dealership I ever been to. It was like living the office tv show with all the charming and funny workers there! From Art, John and Armen they truly are the most interesting sales group in the world!
