Here's how I break down the voters from this poll:
E30 M3:
Correct vote.
E36 M3: This is the only M3 they've ever owned/driven.
E46 M3: This is the only M3 they've ever owned/driven.
E9x M3: Forum Biased voter/This is the only M3 they've ever owned/driven.
F8x M3: Too elitist to vote otherwise.
Other: Throw away vote.
