2019 BMW M3 CS - The body of the M3 CS gets the requisite performance look by way of the power dome on the hood, flared wheel arches and, of course, parts made of carbon fiber reinforced plastic, such as the roof and rear diffuser, not to mention the very cool looking Gurney flap on the decklid. It looks like the very serious performance machine that it is without resorting to a boy-racer rear wing or other tacky accoutrements.
