Talk about a bodacious backside, this picture of the Lamborghini Countach, the supercar once featured on every bedroom wall and sent to us courtesy of Gordon Calder, appears more intimidating today than ever before. Thankfully, Lamborghini are still manufacturing madness, as the insane $4 million Veneno is primed for its first U.S. appearance next week on the lawn at Pebble Beach. As ever, we'll be there too, camera at the ready. Got a shot to share? Add it to the Motoramic group on Flickr, or send us a message via Twitter, Facebook and Google+.
