Lamborghini LP640


I personally think that cars are a bit of a work of art. None more so than Lamborghinis. They really are one of the few manufacturers on the planet that make balls to the wall, crazy sports automobiles that will happily shred their tyres to bring tears to your eyes.

Not only that of course, you'll have great fun in doing so. With that in mind, it is with pleasure that below I supply further information on the Lamborghin LP640 - it is a car and a half!
