The BMW M3 is a high-performance version of the BMW 3-Series, developed by BMW's in-house motorsport division, BMW M. M3 models have been derived from the E30, E36, E46 and E90/E92/E93 3-series, and sold with coupé, saloon and convertible body styles. Upgrades over the "standard" 3-Series automobiles include more powerful and responsive transmission & engines, improved handling/suspension/braking systems, aerodynamic body enhancements, and interior/exterior accents with the tri-colour "M" (Motorsport) emblem. Owner of an E36 M3 stick shift coupe has been one of my best car collections to own.
