I've driven the S60 for four months now and my overall satisfaction is a 10. It's a great car and stands out on the Southern California roads filled with MBZs and BMWs.
After happily owning a Mercedes for over 15 years, I'm glad that I decided to consider alternatives. I looked at Audi, Jaguar, Acura, MBZ, BMW and Volvo.
It's fun to drive a car that you don't see everywhere you turn. Especially one that performs and looks as good as the S60.
