According to the show's organisers, the 2013 LA Motor Show is the 'mother of all shows' - how wonderfully American!

Bertone to celebrate 100th anniversary with Nuccio concept

Bertone will introduce its new Nuccio concept car at the Geneva Motor Show as it celebrates its 100th anniversary. The concept – named after the son of the company's founder Nuccio Bertone, who died in 1997 – appears to take inspiration from the 1970 Lancia Stratos HF Zero, one of Bertone's most famous designs, created by Marcello Gandini.
