Wow, no flies on this group. 1954 Pegaso Z102. I believe this particular car is a Superleggera Coupe by Touring, so not really completely forthright when I said "not Italian." But no one, especially Pegaso, ever called their cars other than Spanish. As to the portholes, almost all Pegasos had some vents on the side, and these included portholes, simple openings, slats, strakes, and whatever else the coachbuilder felt like that day. My guess is that they would be original.
Thanks for playing.
