World-famous supercar builder McLaren has a number of horses in its stable, but the 570S is its most accessible -- and the 570GT is a super-luxurious and actually relatively practical version on top of that chassis. Now, unveiled at the Pebble Beach Concours d'Elegance, the 570GT by McLaren Special Operations Concept is an extra layer of cool on top of that -- and has a superlightweight titanium exhaust and an automatically-tinting sunroof.
