Porsche 550 Zagato Spyder
This Swiss owner told us, this was one of the 5 Porsche 550 spyder build by Zagato. The original was destroyed in a fatal crash during the 1959 Rallye des Routes du Nord in France. Afterwards Zagato build 5 copies. You can read a little more about it if you go to this page. The comments contain additional (the correct?) information. It was not easy to make an impressive sound with a beetle style engine but truly equal length and some special handmade silencers did sure help.
