All the staff was amazing.
All the staff was amazing. Especially our sales person Michael Quezada. The facilities were immaculate and just everything about this place made buying a new car an wonderf experience.
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Thank you to your dealer and your staff for helping us
Thank you to your dealer and your staff for helping us choose the best car for us, special thanks to Yura for giving us good service.
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Amazing experience
I was in the market for the new Sienna XSE with some upgrades and couldn't find what I was looking for. I was in contact with A LOT of dealerships and they were just awful. I finally called Longo and was able to reserve a Sienna XSE that was coming from the factory, with the package that we wanted. David Fearn was awesome, he was understanding and helpful. We had a lot of question due to our previous experience and he was more than happy to help us. When the vehicle arrived we were a little afraid it would be sold from under us but again David was understanding and reassured me it would not. So we were able to relax and come in on our day off. I believe we spent about an hour finalizing everything and then drove home in our new Sienna. Its was such a quick and amazing experience, I definitely recommend Longo to anyone looking for a new Toyota.

recently visited Mercedes-Benz and had the pleasure of
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.

AMAZING!!!
I want to start off with the compassion this place has for the customers. I never once felt pressured for anything when being here and talking with the sales reps. I had the pleasure of doing business with Rami. He took things at my pace, was very understanding and I felt tried his hardest to get me into the car I so desperately wanted. He kept me updated on the car and walked me through each step making sure I was comfortable and answering my questions to reassure me of what was going on. Then came the gorgeous Vanessa who emailed me during the week to make sure my dream car was still available. When I went into the dealership she introduced herself and sat to talk to me even though I was working with Rami. She was very nice and also made my experience that much better. She honestly cared and I could tell by how passionately she spoke to me and could see it in her eyes. Last came Argenis who tried his hardest to get me the best deal I could handle. He was very professional and walked me through everything. He made the experience very comfortable and I am very pleased with my whole experience here. I would recommend 10/10. My best experience by far with any auto group.

Booyeah!
I decided to go to Huntington Beach for my Sonata Sport Plus, instead of the dealership where I got my Elantra from last year, and I was not disappointed. The dealership is friendly and puts clientel first. I wasn’t rushed to do anything, just make my decisions and go. It’s not everyday that people go the extra mile for you. I couldnt get someone to take me there, but the dealership was super understanding and came to take me to the dealership, where we did all the paperwork and i was able to drive off the lot. Not only that, Christina P, the one who sold me the Sonata and also came to pick me up, also had driven to MULTIPLE dealerships to get me the exact car i wanted. Lance was awesome, working with what was able to be worked with, handling finances both in person and even through the phone. Y’all are sweet! My family and family friends are hyundai shoppers, and we all go to the same dealership, so Huntington definitely has our business! ����❤️

This is my first experience with Fletcher Jones and it
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.

Time for a new car?
I was not ready to buy a new car; I bought a ford Fiesta from Cal Worthington of Long Beach 3 years ago and I really loved that car. A few weeks ago someone TBoned us and my poor Fiesta paid the price. I needed a new car. I went to Worthington of LB because they gave me a chance at a car when no one else wanted to. I was right to go there. I was treated with respect, Armando was great not pushy, and direct with questions and answers. I told him which car I was looking at and he got it ready for the test drive; by the time we were back I knew I wanted this car. The paperwork was fast and off I went to meet Joe. Folks ask for Joe M. He was working that papaer work and got me a nice discount. He did not try and sell me anything I did not want. After the car accident I learned that GAP is good to have. I had my sister drive me and Joe said send her home you are driving home. Armando C and Joe M make A great time. I have the Focus now and I'm actually really enjoying the slightly bigger car. No I was not ready to buy a new car but l needed to. I'm glad I went and met these two guys; they made the process easy and pleasant. Thanks gents!
