Fiat Chrysler Automobiles’ luxury brand Maserati continued to enjoy strong sales in May with a whopping 406 percent increase over the same month last year. But the high-end Italian brand plans to go higher still with a lofty goal to expand its annual sales to 75,000 units by 2018. Last month, the company moved 1,144 cars thanks in part to its new mid-size Ghibli sedan. Before the brand reaches its four-year sales goal, it will release a production version of the Alfieri concept in coupe form that debuted in Geneva last March followed by a convertible and then a new GranTurismo.
