One of the better uses of the Ferrari Enzo’s mechanicals, the Birdcage 75th ups the power to a nice round 700 hp. Instead of doors, the massive glass canopy lifts up, revealing a futuristic (especially in 2005) interior. It actually ran, too, as some select media were given access to the one-off beast. A fine way to celebrate the iconic Maserati Birdcage racer and the 75th anniversary of legendary Italian design house Pininfarina.
