Talking about the BMW M3 GTR (E46) isn't about talking about an ordinary car; it's about a legalized cheat that humiliated the competition and became the greatest legend of automotive culture in the 2000s.

It was a weapon of war forged by BMW Motorsport to annihilate Porsche's dominance in the ALMS (American Le Mans Series) in 2001.
