I remember that Pininfarina concept car. I thought those were impressive lines then. Today I would be tempted to make comparisons with the Volhart-Sagitta—the low hood-line between projecting pontoon fenders and deep windshield, compared to the more Porsche-like actual P33 Stradale.
Other cars based on the same Alfa:
Bertone Carabo. This had laminated safety glass thin enough to bend. I wonder if you can get that today?
Alfa Romeo 33 Mugello Spyder
