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!

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

It was a great day when I chose to stop by Mercedes Benz in Long Beach. Ali helped me get into the car of my dreams. I truly enjoyed the car shopping experience because of his hassle free approach. I will definitely be back to pick out another vehicle for my husband.

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

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.

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.

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!

The car offers a smooth ride, powerful engine, luxurious design, and advanced featuress. Making a top choice for comfort and style. overall design was sleek and luxurious.

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!

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.
