I'm sure there's a good reason why you can't buy a car with a full canopy roof. But dammit, I still want one.
Above is the 1996 Zagato Raptor, or Lamborghini Raptor, depending on who you ask. It has all-wheel drive and a 5.7l Lamborghini V12 mounted in the middle. That's all well and good, but all I really care about is that the double-bubble roof flips all the way up. I'm sure I'd look like a toolbag pulling up anywhere with a roof that latches up, but sometimes you have to accept that the world can always use a little theater.
Come to think of it, some of my favorite car designs have canopy roofs. There's the fantastic 2006 Saab Aero X, the greatest Saab that never was.
