Did you miss your chance to pick up that Lamborghini Diablo SE at Amelia Island earlier this month? It ended up selling for $412,000 – far more than the $350k high end of its pre-sale estimate. Well this could be the next best thing… or even better.

It’s a 1999 Diablo GT, one of just 80 made. And according to the same auction house that handled the aforementioned VT 6.0 SE, it could be the lowest-mileage example around.

Produced just before the SE, and right after Audi took over, the GT may have been the ultimate version of the Diablo ever made. It packed the same enlarged 6.0-liter V12 that would later power the SE, but with even more power – 575 hp (583 ps/429 kW) and 465 lb-ft (630 Nm) of torque, to be exact. Which was even more than the SE’s and was directed solely to the rear wheels.

The GT was as close to a race car for the road as we had ever seen. It had a stripped-out interior and a more extreme aero package than any other street-legal version of the legendary Raging Bull. In fact it was never certified for sale or use in the United States.

This example was delivered to one Peter Worm, a German doctor and businessman based in Malaysia. Worm evidently enjoyed racing his Diablo SVR and Diablo GTR on track so much that he apparently couldn’t resist ordering up this Diablo GT to drive on the road. But, in the end, he didn’t really drive it.

In the nearly two decades since this twelfth example in the series was made, it’s seen only 171 miles (276 kilometers) of road use. It even has the carbon-fiber briefcase it came with, which is about the only thing you’ll fit under the nose with that air duct in the way.

With such low mileage, you can bet it’ll attract its due share of attention in Monaco, where RM Sotheby’s will sell it off to the highest bidder on May 12. The last one we saw come up for auction sold (by the same auctioneer) in London a couple of years ago for £515,200 – or about $730k in today’s money. And that one had 6,900 miles (11,100 km) on the clock, so you can bet this one will go for more.
