The very first production version.
The Lamborghini Countach was a groundbreaking vehicle in more ways than one, including new lows in the area of rear visibility. Most people who get the chance to drive one are far too excited to care, but the design department at Lamborghini was genuinely concerned about this, and the prototype was given a periscopic rear view mirror, with a tunnel in the roof to make said mirror usable.
The mirror was scrapped before the production car debuted, but early production versions of the car kept the tunnel. These cars got the nickname "Periscopio", and this is one of those cars. When the LP400S debuted in 1978, the roof was made flat, so only about 150 Periscopio units were ever produced. One of these relatively simple and uncluttered versions of the car will be going up for auction by RM Auctions in Paris in February. Making the car even more rare is the fact that it's right hand drive. There's no estimate of what it's worth, but it is in great shape.
