Some kind of people, from 50th to 60th aged gentleman, Roadster is the youth they haven't ever had. In Japan, people in that age have been working so hard from poorness after WW2. They dreamed someday they drive sports car like Blitish light weight they often seen.
Roadster is their "late youth" that they haven't had when they were young.
