Smooth and Powerful Convertible!
 I bought the convertible three weeks ago and after 1500 miles I have to say that this is one sweet and powerful performance machine.  Around the city, the gearing and torque make the ride seamless, and on the highway the car has a blacktop-eating ride that wants to run much faster than the law allows.  Very happy with my CPO purchase - the car had depreciated $50K+ in three years, so with the extended CPO warranty to 100K miles and with BMW NA including free no-cost maintenance out to 100K miles as a sales incentive, it also fits the bill from a value standpoint.  sweet convertible that gets many a look
