Traditionally, there hasn't been much difference between Lamborghini's concept cars and the production machines. The borderline-outrageous styling and performance filter down quite well from the drawing board to the pavement. The Concept S is just that — a concept — except that it's a fully-functional, street-legal car. Building on the Gallardo platform, Lamborghini created a convertible like no other. There is no canvas or retractable hardtop. The Concept S is a true roadster, with the occupants exposed to the elements. The striking twin-cockpit design separates the driver and passenger and reinforces the look of single seat racing cars of the past. A truly rare car, this one-off drivable concept is the ultimate spyder, with only 115 miles clocked in the last 11 years.
