I had a smooth and excellent experience purchasing my new Mercedes. My sales agent was wonderful?never pushy, truly listened to what I wanted, and made the process stress-free from start to finish. Everything was transparent with no hidden agendas, and I felt completely comfortable and confident in my decision. I highly recommend working with her if you?re looking for a professional and enjoyable car-buying experience.

I had the best and worry less experience with this dealership, it took only 2 hours since I stepped in till I left wit my brand new Mercedes Benz, Ali, the sales representative is wonderful, He is so welcoming and kindly found the exact car to my taste and an awesome test drive experience over the best view of Long Beach and ocean, found a GREAT deal and negotiate pricing and conditions, David, the sales manager was really generous, he generously added an extra deal and made it even greater for me, the whole process of documentation and contract went so smooth and fast and they clearly described and clarified all terms and numbers, car delivered clean, shiny with no detailed missed and Ali went trough all features and described them patiently, the other five star thing was that they DIDN'T try to sell any additional non sense and I REALLY appreciate that, I'm so happy with my new Mercedes Benz and highly recommend all my friends and family to go to Mercedes Benz of Long Beach for their next car buying,

Well, our experience with Tony was Fantastic! We found a car on the internet that we wanted and proceeded to go out there to purchase. Upon our arrival, Tony greeted us without delay and processed our request. We were out of the dealership within 1.5 hours, now that's a record! He got us our approval in a timely manner and it was all good!!! I would definitely work with them again. Now about the markup, it seems all the dealerships mark up and in order to stay in business so I don't worry too much. Plus the fact the car we purchased was in pristine condition with low miles it was worth the markup and the drive. I am a satisified!

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!

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!

Ashley is top notch with knowledge and service and patience! Everyone at the dealership is helpful and accommodating. Thanks for everything, Ashley!

I had such a great experience at Mercedes-Benz of Riverside! Christian was incredibly helpful from start to finish—he really took the time to listen to what I was looking for and helped me find the exact C300 I had in mind. He was patient, knowledgeable, and made the whole process smooth and stress-free. I couldn’t be happier with my new car! I would definitely recommend Christian and this dealership to anyone in the market for a Mercedes.

Christian and Rob were the absolute best to work with at Walter’s Mercedes Riverside. They are very professional, honest and straightforward. So happy with our new purchase and the entire process.

Overall everything was very satisfactory! I have been purchasing my car through Mr. Bang at House of Import for the last 20 years. He is very straight forward and trustable sales person!

Lingling was as always the best of the best in helping me find the best car for me. She is always understanding and helpful. She?s incredibly friendly and I always appreciate her. We have gotten cars with her for over 20 years now.

Great service and smooth transaction all the way. Very happy with my car and our sales person. The Used Car Manager was awesome and very kind. We Weill sure be back

Todd and his team were outstanding. They found just the right car for some friends of mine who asked me to shop for them. Customer service was exceptional. Pricing was very competitive, and the overall experience was a 10+. I highly recommend that you give these professionals a shot. You will be pleased.

We purchased a pre-owned 2017 Corvette Stingray Z51 from Mercedes-Benz of Foothill Ranch, and the experience was outstanding from start to finish. MB of FH provided a detailed pre-owned reconditioning summary along with the vehicle’s CARFAX, so we had complete confidence in the history and that everything had been thoroughly checked and serviced. Our Sales Professional, Conrad Cave, made the entire process smooth and stress-free. He was upfront, transparent, and answered all of our questions without any pressure. The Stingray was in excellent condition—exactly as described—and we couldn’t be happier with our purchase. We highly recommend Mercedes-Benz of Foothill Ranch and Conrad Cave if you’re looking for a quality vehicle and a top-notch buying experience.
