SHOW ME THEM!! Here are my top 3. I ain't no writer, so I'm gonna keep this short.

3.) Ferrari 512m/Ferrari 512s

Honestly you could comprise this whole list with Colombo V12s. Ferrari was pretty good at winning Le Mans, and then they got hit with 'Murica.

2.) Porsche 917

Come on, how can this not sound good to anyone? SERIOUSLY

1.) Jaguar XJR-8/XJR-9

I can hear you right now, "How come no 787B" because V12, that's why.
