Really? One can say, "En kan leie en leiebil?" What would be more common in casual speech, "en" or "man"? In written form? (Takk in advance) [Edit: this version of the question was multiple choice.]
In casual speak either 'man' or 'du' would be common. In written form I think 'en' and 'man' serves different somewhat purposes, so they're both common. ('man' can only be used as a subject).
"En leiebil kan leies." Fungerer det ikke med passiv?
