The BMW M3 is a high-performance sedan that has been produced by BMW since 1985. The M3 was originally only available as a coupe, but it is now also available as a sedan and convertible. The M3 is the most powerful and fastest car in the 3 Series lineup. It is also one of the most expensive cars in the lineup, with a starting price of $64,900. While the M3 is an expensive car, it is still a relatively good value when compared to other luxury cars. For example, the Mercedes-Benz C63 AMG starts at $70,900, while the Audi RS5 starts at $69,900. The M3 is also less expensive than some of its British rivals, such as the Jaguar XKR-S ($99,900) and the Aston Martin Vantage ($120,900).

The M3 is a great choice for luxury car buyers who are looking for a high-performance car that is still relatively affordable. It is also a good choice for those who want a powerful and stylish car that will turn heads when driving.
