The most striking aspect of a race car isn't always the way it looks. Most of the time, it's the way it sounds. What's the best sounding race car of all time?

One of my all time favorites has to be any F1 car powered by the Cosworth DFV. There's this amazing wail that comes out of any car powered by the engine, which is also one of the most successful, longest lasting, and versatile engines ever put in a race car.

What do you think? What's the best sounding race car of all time?
