We were very pleased with the service provided by Vinod
We were very pleased with the service provided by Vinod and Nicholas from beginning to end. Vinod was very thorough in his assessment and understanding of the type of car we needed and the budget range we could work with. From that point on, it was a matter of a day or two until we found what we were looking for. Another two days later the car was delivered by Nicholas at our door looking and driving great.

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.

Bao has been awesome great experience would come back for my next car Was in and out fast
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.

Best Used Prices in The Bay (at least)
I tried! I called to haggle and I even came in and went back and forth but I had to try. It really was the best price I could find on any similar S model so I planned to buy it anyway. I did get a great hat and pen though! Thank you all and happy holidays

My 1st Mercedes-Benz
$110k is quite a bit to spend on a vehicle that I don't need so the service should feel different, almost like you are paying for special treatment...we that is just what I got. I feel great about the whole thing and I will be a Mercedes-Benz driver for life now! Gave it almost a month before writing this review but I am in love and want to world to know. Just don't get the same exact car as me :)
