Maserati GranTurismo

The Maserati GranTurismo is a swooping Italian grand tourer that marries dramatic, museum-worthy styling with a sonorous exhaust note that insists on being noticed. It’s the kind of indulgent cruiser for buyers who want theatrical presence and a luxurious, long-distance demeanour rather than everyday practicality.
