Green machine: Flickr photo of the day

Only ten Prinz Heinrich Benzes were ever made, this one from circa 1910. Four of these rare machines featured on the lawn at this year's Pebble Beach Concours d'Elegance, and we lucked into a spot in the 88-mile Tour d'Elegance in the back of the number 36 Prinz Heinrich. You can read our report on the car here, and thank Chris Willis for the cool shot. Post your photos to the Motoramic group on Flickr, or send us a message via Twitter, Facebook and Google+.
