It is a beautiful car - it's the 300SLR, the car in which Stirling Moss famously won the Mille Miglia...can't remember the year.
Now to re-use the SLR moniker on that pimp-mobile they're bringing out is sacrilege! It would be like some long lost descendant of DaVinci photographing a hooker with her tits out and calling it "Mona Lisa" 
The racing Mercs of the 1950s were all extremely nice looking cars. However, their recent styling leaves a lot to be desired (with the exception of the SL).
