At this year's Monterey Motorsports Reunion, spectators were treated to a dream come true in the form of a 1969 Porsche 917K barreling down the track in all of its Le Mans crushing glory. It's 4.5-liter flat-12 engine roars with unbridled menacing and what's better is that this particular car has an estimated worth of over $20 million dollars. You'll never see something like this again.
