All I want for Christmas: Part 8 Lamborghini Marzal, 1967, by Bertone. Designed by Marcello Gandini, a concept powered by a mid/rear mounted transverse 2.0 litre 6 cylinder engine that was one bank of Lamborghini’s 4 litre V12. It was only ever intended as a show car though elements of the design fed into the Espada, also designed by Gandini, which was Lamborghini’s first four-seater.
