The Bertone Jaguar Pirana is very interesting car for a number of reasons:
1. Its looks like a Lamborghini
2. Its based on a Jaguar E-Type but less beautiful, also also heavier and slower
3. It was conceived not by an automaker but by journalists.
The Telegraph in the UK started by buying a 2+2 E-Type chassis and shipped it to Italy to have Bertone design a body for it. It made its debut at the 1967 Earls Court Motor Show.
