The whole process was stress and drama free. They were able to deliver on everything conveyed. I would highly recommend W.I. Samuelson to friends and neighbors.

Ali Mahmoudi at the Mercedes Benz dealership in Santa Monica was professional and helped us throughout our buying experience. We highly recommend him. He will help find the car you are looking for.

Best experience we've ever had at a dealership! The car was priced at the low end of KBB and they gave us more for our trade in than we anticipated. The process was quick and aggravation free!

I went in knowing I wanted an EV. The vehicle I drove away with exceeded my expectations. I?ve been looking for other EVs on the market and EQS SUV 580 makes other EV looks like toy cars. This vehicle is so luxury and smart. Mercedes thought of everything. And the air freshener is amazing.

Souharda totally screwed me over. Sold me a car that basically fell apart on the highway. The bumper was not attached and fell off on my way home. I had to reattach on the side of the road. Then the car immediately started having issues that have costed me thousands and they have not done anything to make it right. All they do is IGNORE my emails and phone calls. And you guys are suppose to be a reputable dealer?? You act like a shady used car lot. DO NOT SHOP HERE!
