TCC’s Bottom Line
The 2017 Maserati GranTurismo is getting old but its Ferrari-inspired performance and sensuous styling and still appealing. The 2017 Mercedes-Benz SL-Class isn't quite a sports car, but it's a rapid, open-air touring coupe extraordinaire. The 2017 Porsche 911 is a toe into the waters of modernity with a base turbo engine that gets good fuel economy. Don't be fooled; it's every bit the super car it always has been.
