I was just watching this vid, and this reminded me of
The Lamborghini experience I had as a child. I was walking along the Strip in Las Vegas one night and saw a Diablo SV, a silver one with black wheels and the black "SV" emblazoned across its flanks. The driver was kind enough to rev the thing for me. It was a near religious experience.
Lamborghini Diablo SV's my favorite sounding Lamborghini. I could hear the thing for a mile before it came into my sight, blew me away completely, then left leaving only a trail of sonic boom from is magnificent engine. The thing's so loud, yet tuneful. And the when the foot touches the pedal, all hell breaks loose.

I don't care so much about the new Lambos. They don't sound as mad, angry, and deadly, a bit of a let down. That's just me
