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.

It won’t set your pulse racing on a back road, but it will make school runs, commutes and grocery hauls feel pleasantly civilized — a reliable, slightly posh companion for real life.

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.
