Maserati has been working diligently for a while now to deliver the GranTurismo into the long run. The Italian high-performance top-dollar coupe/convertible has come a great distance from its basis as a collaborative effort between the Trident and the Prancing Horse firms. The unique GranTurismo’s exceptionally curvy exterior and opulent inside are as conventional to the nameplate as its Ferrari-derived 4.2-liter V8 engine married to a 6-speed computerized or 6-speed automated handbook transmission.
