Still in the sixties , designers used to do a lot of prototypes, and Frua is one of the most famous. On this german webpage, there are links to the several cars he made.
Some are original and famous : the Maserati Mistral 1963 /68 is the one I remember when thinking of the italian designer Pietro Frua, in the USA you may remember the late version of the AC 428 fastback.
The language is german. The history of this Pagoda "shooting brake" is interesting. The car was in the sixties in Switzerland (1st owner), later owned by a spanish diplomate(2nd owner) who imported it to Madrid in 1984.Then, it had about 5 other owners in Toledo, Cordoba, Madrid and even in Gran Canaria island. It had a restauration, changing the plexiglas window, and got another engine in 2002, after the 1st one broke on the way to Sevilla.
