For a Singapore contest, now finished, the above Mini Cooper was parked in secret location and those who found the car could play PGR3 and potentially win an Xbox 360 bundle. Sister site Xbox 360 Fanboy found this on their Flickr feed and discovered its origin. The Flickr account in question contains a plethora of pictures from the same car show, but only one of the 360-mobile. The fate of this car is unknown.
In the interest of being non-biased, here is a Sony car stereo from the same Flickr account. Sorry Nintendo, you already had your post on themed transportation.
