No surprise that my two favorite attractions at San Francisco’s auto show this year carry the same emblem.  While the flawless 1971 280SE 3.5 Cabriolet steers nostalgia, the striking 2013 SLS dictates an exciting future.  From yesterday to tomorrow, the remarkable timelessness of Mercedes-Benz automobiles deserves a nod once more.  At the same time, Sammy Davis Jr.’s 1963 Rolls Royce Silver Cloud III isn’t too shabby either, another “star” to grace the Moscone Center this time around.  Altogether, here’s to another good show!
