Lamborghini are going to use the Pebble Beach Concours d’Elegance to unveil their Roadster version of the ultra-exclusive Centenario. The reveal will happen this Friday so hopefully we even get a leak or two today. Lamborghini plans to build 40 Centenarios in total, 20 Coupes and 20 Roadsters, with a price tag close to $2 million. Every example was sold prior to the car being unveiled in Geneva.
