If I Were Rich!.. (1972)

Michalis and Filippos, a pair of inseparable friends and hard-working grease monkeys, aspire to strike it rich. With this in mind, the impecunious companions pluck up the courage to take for a ride the expensive car of the garage's best customer and affluent businessman, Aristides Tsitsis, to pose as wealthy bachelors. Before long, a chance encounter with Aristides' beautiful daughter whom they've never met, Mitsi, will lead to an innocent ruse and unexpected love. However, what happens if the wealthy entrepreneur finds out that, not only his car is missing, but also he's about to lose his beloved daughter, too?
