We recently acquired a 2025 MB 450 GLEe from Walter’s with the help of Christian Aparicio. We our longtime MB owners so it’s a high bar with us but Christian exceeded all expectations. We couldn’t be happier and will certainly contact him the next time we need a MB. Thank you Christian!

Anthony went above and beyond expectations to get the vehicle of my choice. Would highly recommend friends and family to purchase their next vehicle here.
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.

Sales customer service was the best experience ever !
Sales customer service was the best experience ever ! Candace could not have been nicer, more accommodating and made the process painless. Alex facilitated the transaction and the same. we are very happy and would continue to buy from her and Alex! You can buy a car anyplace, why not where they take great care of you instead of the stress normally associated with buying a car. 10 stars....

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.
