The Hondina Youngstar was a Zagato-bodied roofless "beach car" with no doors and bug-eye headlights, which was based on the Honda N360. Zagato's Honda Hondina was one of the first sporty kei cars ever built. It rode on the same platform as the tiny Honda N360 and used its 360cc two-cylinder engine, but it featured an open-top body with an integrated roll bar and no doors. Still, in its infancy, Honda wasn't interested in taking the Hondina past the concept stage, but it perhaps remembered the concept when it designed a topless, mid-engined kei car christened Beat in the late 1980s.
