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.
