New and used 2025 Mercedes-Benz GLS 450 SUVs for sale near Avocado Heights, 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’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

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.

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!

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.

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

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,

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!!!!

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

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.

I recently worked with [ Jeff ] to get my car, and the experience couldn’t have been better! They were professional, kind, and made the entire process smooth and stress-free. Highly recommend if you’re looking for someone who truly cares and goes the extra mile! 🙌🚗💫

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

This is my first experience with Fletcher Jones and it has been a good one so far. Buying a car long distance, sight unseen is always a bit of a challenge and potentially a risk. I feel very good about the responsiveness and customer care provided by Fletcher Jones staff. As car delivery is still in front of us, the jury is out on this experience, but I anticipate a very positive outcome. Fletcher Jones reputation provided a lot of confidence.

It was a great experience from beginning to end. I got exactly what I wanted and it was delivered to me in perfect condition. I can’t thank them enough.

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.

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!

They are a great group of professionals! I had the best experience! I highly recommend ANYONE to go and see them. No matter any problems you may have they work hard to find a way to help you out! Thank you again for putting me in a wonderful BMW X1, I LOVE it!

AMAZING SERVICE! Dan went above and beyond to make sure we got the car that fit us the best. He didn’t mind us having as many test-drives as we needed and helped us get approved for the 2020 Audi Q5 when we decided. Not pushy, respectful and very helpful! Will come back for an upgrade!
