You smile just thinking about driving it
 Near perfect balance of power, transmission shifting, suspension, road feel, braking and steering.  Power top quick enough to raise or lower at even a fast stop light without feeling rushed. Sound system brings out amazing detail even with the top down. Trunk space provides the ability to use this as my full time vehicle, easily taking two suitcases, a large duffel and a fully packed computer briefcase. My only suggestion is that a new buyer opt for wheels that have a minimum of tight spaces, as you're going to spend a lot of time dealing with the legendary BMW brake dust buildup.
