Reine Geschmacksache (2007)

dir. Ingo Rasper Wolfgang Zenker, a middle-aged traveling ladies' fashion salesman is in dire straits: his deadly rival Steven Brookmüller is threatening to steal his best customers and he's lost his driver's license. Desperate to stay one step ahead of his young enemy salesman, he cancels his 20-years-old son Karsten's holiday and employs him as an unwilling chauffeur. Things go from bad to worse - the bank is after him, the taxman catches up with him, his wife threatens to leave him, and Karsten falls in love with his rival.
