The M4 is the high-performance member of BMW's 4 Series compact coupe lineup. While mechanically similar to the
M3 sedan, this car boasts more style and variety with hardtop, convertible and four-door Gran Coupe variants more classy than showy, inside and out. Despite racetrack credentials, the M4 is also a viable four-season car -- providing it's equipped with weather-appropriate tires.
