 I was approached not long after purchasing the SL by a gentlemen who has owned a good number of exotic and sports cars.  In his words, "the SL is what all cars want to be when they grow up".  I could not agree more.  You may find a sportier car or two, a better looking luxury car, or a car that covers great distances in extreme comfort; but the SL does all of that, and more.  This car loves to eat road, top up is like a coupe; solid and silent.  Top down is like, well, a high performance convertible.  The SL has become our grand touring car and it has proven itself to be most worthy in every instance.  We went the CPO route, which lessens the pain of the check book, but provides solid Mercedes warranty and support.  Drive the other contenders, then drive an SL.  It continues to amaze with it's power, torque, ease of operation, and rock solid build quality.  And while the looks may be contentious to some, this car draws admiring looks in even the most discerning crowds.  It does not disappoint.
