news to me, some cars that left the factory made of fiberglass that aren't Corvettes

The Lotus Elan, 1962-1999. The Lotus Esprit 1976-2004. The Lotus Elise, 1996-2021

The DeLorean, unknown to me, the stainless steel outer skin, are actually fixed to a fiberglass monocoque, which was then attached to a steel frame.

The Meyers Manx, won't surprise anyone to be made of fiberglass... but it simply hadn't occurred to me to think of it when discussing fiberglass sports cars. And it is. 

BMW Z1, 1989, 90 and 91surprises me. I haven't ever heard about it being made of fiberglass

Lancia Stratos, 1973-78 is another complete surprise.
