Courtesy of an email from Gerald F., here's an amazing sound. Someone had the bright idea (?) of converting an Aston Martin V8 Vantage GT4 road racing car into a rally car. You can read more about the project here. Gerald sent links to a few videos of the car in full song during the Rallye du Var in France, last November. The sound is indescribable! Hear and see for yourself.
And here's what a couple of stages looked and sounded like from inside the car. The driver is French rally ace François Delecour.
I'd have paid good money to be on board for that . . .
