Alternatively, with fuel prices lower than they've been for years, and the world-wide demand for luxury 4x4's still increasing, maybe Maserati haven't missed the boat. But I'd still prefer they left this to the likes of Land Rover and got on with making more exotic offerings. Unfortunately there simply isn't enough volume/profit in such cars.
Look at Porsche. The 911 is awesome, but out of their range of cars, it sells the least. The best seller is the Cayenne, then the Panamera. Big ugly cars cars sell more than small, fast, exotic ones. Sad really.
