The E39 M5 gets an automatic entry in the debate for best sedan ever made - if not best vehicle period. The design is timeless. The build-quality is superb. The performance speaks for itself. This is a car that does EVERYTHING right. Press the "Sport" button to invoke mind-bending acceleration and seemingly inexhaustible grip. The braking is par excellence. The frame has a rigidity akin to the Hoover Dam. Response, whether throttle or steering, is instantaneous. Every moment in an M5 can make you aware that this is, truly, a very special machine.
Everything. Acceleration, handling, braking, response, transmission, color- changing metallic paint, the rims, luxury features out the ying-yang. The E39 M5 represents the best of engineering and design from what is arguably the world's best automaker.
The paint is beautiful but, like most environmentally-friendly mixes, it chips too easily.
