Rarely has anything been romanticized as much as driving down the highway in a two-seater convertible sports car, top town, wind blowing through the cab, tunes blasting on the radio. It's an image straight from the movies, a fable of glamour and automotive bliss, but it's also real. The fable of the top-down convertible sports car with fantastic acceleration, blistering speed, lively handling and dashing good looks is readily available to the driver of the 2013 Porsche Boxster S.
