For some time there was a rumour that Mr Giugiaro had something to do with the Alfa 156 design (pre-His-facelift of course)
And I did found something:
“In actual fact, Giugiaro contributed to the 156 during the initial stage of the project.”
Maybe it was a bit like an initial design of Gallardo, later finished by Mr Donckerwolke; or a wind-tunnel contribution to MC12 project?

And more
“Eng. Bandiera also touched upon the styling contribution driven through by Giugiaro in the realization of the ongoing 156 model.”

Both from december 2002, so pre-Giugiaro-2003-156-facelift
