Unlike any other car....
 I looked at every "similar" vehicle - Porsche 911 and Cayman, SL-Class - but just couldn't find the right fit.  I am so pleased with my decision!  The car has enough "sporty-ness" to feel like a performance car, but without the harshness or diminutive stature of so many other "sports cars" (I'm 6'3" and 250 lbs).  To say that it is in a class of its own is too trite, but there really isn't anything comparable.  Thus far it's been a whole lot of fun.  I'll let you know what long-term ownership is like.
