If you ever felt like wanting a proper one-off Lamborghini, this might do the trick: it’s the 2006 Lamborghini Concept S and, more specifically, the only fully functional example in the world.

It was first presented as a non-running design study in 2005 and basically is an extreme spyder version of the Gallardo, with twin cockpits side by side.

One year later. the fully functional example you see here was ready, featuring redesigned windscreens that were lowered for homologation purposes. Lamborghini intended to build 100 cars for its best customers, but the whole project was abandoned due to the exceedingly high cost and time-consuming production of the Concept S.

After failing to sell at a 2015 auction, this beautiful one-off Lamborghini is ready to cross the auction block again, this time at the RM Sothebys Monterey event on August 18.

It has covered just 180km (111 miles) since new and has participated twice at the Pebble Beach Concours d’Elegance. Will it sell this time? We’ll see…
