Topless supercars have come a long way since Lamborghini first chopped the roof off a Diablo, transforming it from merely sketchy to highly suspect. Back then, convertible versions were just a means to hoover up dumb money, a nod to buyers just barely more likely to take a V12 sports car to its limits than arrive in…
