Maserati GranTurismo Convertible (www.maserati.com), which might be the most beautiful topless GT on the planet. If one requires more pragmatic reasons to consider the $139,700 GranTurismo, he or she can put foot to floor and experience the performance of a Ferrari-engineered V-8 engine with an exhaust note that pales only—and barely—to that of Ferrari’s grandiloquent 458 Italia. The GT is sufficiently spacious for four full-grown friends to motor in the type of comfort ordinarily associated with prosaic sedans. This car is a dream to drive fast, but it is also rewarding when taking in the town. Make no mistake: This is a full-size GT, based on the proven Quattroporte platform. Like that sedan, the interior of the GranTurismo Convertible is lavishly trimmed in rich leather and wood that render the GT beautiful on the inside as well as the outside.
