1999 Lamborghini Diablo GT
It might share the Diablo name with the SV and VT that debuted the same year, but this 1999 Lamborghini Diablo GT was an entirely different beast. The most track-focused on the group, its V12 engine jumped from 5.7 to 6.0L, increasing horsepower to 575. All that power was delivered to the rear wheels via a five-speed manual, while a dramatically different body crafted primarily from carbon fiber provided added downforce and air to the engine. With only 171 miles on the odometer, this example — number 12 of just 80 ever produced — may be the most pristine example left in the world.
