The formula here is simple and modest. It's Don Quixote & Sancho Panza by way of Abbott and Costello: one fellow has the wacky, ambitious idea, and the other fellow tags along because his loyalty is stronger than his intelligence. Misadventure follows misadventure. Meanwhile, although originally the idea man thinks nothing of going to Germany to sell a luxury car-- presumably he could have sold it somewhere else, but he happened to have a German price list at hand and worries only about making sure his parents don't know his destination-- his bad luck awakens latent thoughts of the old genocidal Germany, or his latent thoughts of the old genocidal Germany awaken bad luck.
Is this a drama or a comedy? There's nothing wrong with a smattering or an undertone of serious issues within a comedy; you could argue that there's no good comedy without them. But I think that this one loses its balance for a moment or two when it stops being funny but can't be taken seriously either. The characters have comic appeal, but there isn't an emotional appeal they can rely on when the comedy is waived.
