If the Countach set Lamborghini on its course as a maker of dramatic supercars, it was the Diablo that refined the Sant’agata Bolognese firm’s mission. At least as outlandish to look at as the Countach, the Diablo that arrived at the dawn of the 1990s was raw and ferocious, but a little more refined with luxuries like power windows and adjustable seats. Within a few years, power steering and anti-lock brakes began to make the Diablo more drivable, but it was the arrival of all-wheel drive with 1993’s Diablo VT that took Lamborghini from childhood bedroom poster exotic to truly advanced, 21st century-ready supercar.

The Diablo VT Roadster was unveiled in late 1995 with an electrically operated carbon fiber targa roof that tucked ahead of the engine cover when stowed away. A year after Audi took over Lamborghini, the German brand pumped cash into refining the Diablo’s interior and revamping its headlights—not to mention adding variable valve timing to its V-12 engine and fitting upsized Brembo brakes. The 1998 takeover by Volkswagen caused several changes to be made to the Diablo family. Revisions to the VT Roadster included fixed composite headlight lenses, a revised interior, 18-inch wheels, antilock brakes, and increased power to 529-hp.

The 1999 Diablo VT Roadster presented here takes full advantage of those updates and is one of the last imported to the United States. It shows only 18,000 miles on the odometer and thanks to a full 3M Clear Bra, it is essentially a time capsule. Believed to be one of a mere dozen painted in Titanium Silver, the Diablo is especially eye-catching thanks to its factory spoiler and 18-inch chrome alloy wheels. Thanks to having been preserved in a private collection, the Diablo VT has not been modified in any way.
