I saw this image and had to find out more about this incredible looking car. It is a Maserati A6GCS with a body by Pininfarina. There were 6 of these specially built Maserati's. Four were coupes by Pininfarina and two were spyders, one by Vignale and one by Frua.
Amazing cars and very collectible. Some were even rebodied again. I found some more information on this Maserati here but not much on Frua. If anyone knows what happened to the Frua company I would be interested.
