Adam Canfield, better known on YouTube and Facebook as AdamC3046, was fortunate enough to have just such an experience while walking around London recently, and found a Ferrari 275 GTB parked on the side of a road.
It seems he arrived at just the right time, too - as he stopped to take photos and shoot some video, the car's owner came outside, gave him a look at the engine and then started it up and drove away. Canfield shared a video on YouTube of this special Ferrari's short show, and the sounds are simply stunning.
