Looks Familiar???

The sierra was also available as a convertible which may have even more familiarity with the 412?

The front of the Sierra is very similar to the stunning Monteverdi 375S. It's very different to the blunt nose of the 412. As for the rear end, the Sierra is so sharp and angular it makes the 412's rear end look positively curvaceous!

I believe any perceived similarities are purely coincidence.

I don't think there is any question that the 412 is a Zagato design. Realistically it's unlike anything else, which to my mind is very typical of Zagato designs, they are quite unique.

Incidentally, I have just come across something which suggests the Sierra was styled by Carrozzeria Fissore, contrary to my earlier post in which I suggested that Peter Monteverdi designed it himself. The Fissore brothers apparently built the bodies for the 375S, (as a result of an introduction by Frua).

Monteverdis I know about, as I used to own a 375L. They were in fact Monteverdi designed, as was the 4 door Range Rover. Fissore had some input I am sure, but the final design was Monteverdi. It worked well on the 375L and Range Rover, but the Sierra... well, nevermind.
