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.

Hassle free experience when I went into get an oil change
Hassle free experience when I went into get an oil change with the help of Branden. Upon completion of service, I received an easy to read report outlining the results of inspection. Service department was very professional and helpful.
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.

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.

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.

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.

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.
