Even though my Gladiator was in the shop for nearly 8
Even though my Gladiator was in the shop for nearly 8 weeks due to a parts shortage, I had a very positive experience in dealing with the service department. Michele is a top notch service advisor, who genuinely cares about her customers, and is quick to return calls. Thank you Michele, you have a return customer in me.

Purchased a Mercedes-Benz E55 AMG
I purchased a used Mercedes-Benz E55 AMG from the Carmax in Costa Mesa, CA about a month ago. I started out by calling the Carmax and reaching a sales agent. She worked with me by setting aside the car so that I could fly down to pick it up. She picked me up from the airport about 15 miles away from their dealership. When I saw the car, I found some minor cosmetic issues with the car and Carmax assured me that they would repair them at my local Carmax in Roseville, CA. I will be writing a review about that Carmax as well. They issued me a form stating repairs to be done at my local dealership. I informed the salesperson that I would be pushing the car a bit and she was fine with it. After the test drive, the car seemed to be in great condition, so we headed in for the paperwork. The appearance inside of the dealership building did not convey a welcoming feeling though. It felt like a warehouse with desks in it. The people within the building were nice and friendly though. The paperwork was pretty quick as I already had a loan check from the credit union. It took about 30 minutes and then I was on my way. Overall, I would say the experience was positive.
2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

The building is absolutely gorgeous and as soon as we
The building is absolutely gorgeous and as soon as we walked in we knew it was going to be a good day. Every detail, from the Bang and Olufsen sound system to the minimalist decor, spoke of elegance and class. We walked over to Robert (Bobby) to ask a question about our visit and he was the perfect person for this. Instantly, he asked a few questions to us and we were on our way. He engaged with our daughter so that she was comfortable as we got down to business. Everything was straightforward and transparent which we appreciated. Each time there was a potential challenge, it was turned into an opportunity and we left happy and satisfied! This is our second Genesis, so we knew what we were buying, we just had no idea WHERE that was going to be. We are in the market for another Genesis in about a year or so and there is no doubt that Bobby at Genesis of Ontario is the one we want to help us with that too! As people of color, it was important to us that we were treated with elegance and class and that's exactly what we experienced. Great job Bobby!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

We want Axel!
We want Axel! We have been in the market for buying a used car and had the chance to interact with a lot of used car salesman that left a sour taste. Coming into Cerritos Nissan, I was on my guard because of the predatory experience in this industry. However Cerritos Nissan does it different. After talking to a car sales agent named Axel on the phone, he clarified that unlike other used car companies Cerritos Nissan does NOT have MANDATORY ADD-ONS to mark up the price you see online and was also able to send us *custom* photos of the car we were after. When we arrived to the dealership we were greeted by Axel who was ready to tour with us (did not make us wait) and was extremely knowledgeable and patient as we examined the Vehicle in great detail. Axel is a different breed in terms of how genuine he is about the cars he sells. When we noticed defects in the car he did not brush us off and talked to his manager to see what he can do for us. After 2 visits to the dealership we purchased the car and ever since Axel has been there along the way, checking up on us. The rest of the crew in Cerritos Nissan is also great, hardworking, professional and are multiple tiers above anything else we have seen during our car search. I highly recommend Nissan Cerritos for their honesty and professionalism and if you are looking for a knowledgable, attentive and honest car sales agent ask for Axel!

"Top Notch" Luxury Car Buying Experience!
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!

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.

This review is long overdue.
This review is long overdue. Dominique Torres has assisted us multiple times since we got our EQS about a year ago, and each experience has been outstanding. She’s always been a pleasure to work with – easy to reach, quick to respond, and proactive in providing timely updates. Most recently, I had an issue with a headlight. I called Dominique in the morning, and she told me I could bring the car in later that same day. I stopped by House of Imports after work, and Dominique promptly received the vehicle and took care of everything. She even offered a courtesy car in case mine needed to stay overnight, but the issue was resolved in about 30 minutes, and I was back on the road in no time. That’s what excellent service looks like. In recent years, I’ve noticed a general decline in customer service across many places – but not here. Its’s refreshing to work with someone like Dominique who consistently goes above and beyond. This is exactly how you retain clients and turn them into repeat customers.
