New and used 2026 Mercedes-Benz AMG GLC 43 SUVs for sale near Diamond Bar, CA

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!

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

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

I went to see my service man Rob Draper today, it was a fantastic experience! Rob Draper never let me down, he is such a wonderful person to take care of your service needs!! Thank you Rob Draper!!!!

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.

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!

On November 25th I went to the Mercedes on Ontario, and was looking to buy an electric car around 7pm in the evening, I was looking at the EQB 350 when this very nice sales representative Abel Vargas helped us and was very nice and interactive explained to us what was good about the electric vehicles, at the end of the point of buying the EQB 350 the transaction at around 2am Black Friday after hours but I will like to mention excellent and outstanding sales person human being his name is fadi batarni I had a situation where I had to call him, a couple days after but was out of town but still answered right away, like always nice friendly and helpful manner, and I really appreciate the help and appreciate the huge help on purchasing my EQB 350 Thank you much guys I really like my car.

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

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!

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!

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!

Honest and straightforward. They made sure the used care we bought was operating correctly before they sold it to us.

Superb all the way around!!! Never had a more pleasant experience with a dealership. Giovanna, Greg and Fred all amazing.
