"I must pay for the car today". I think I remember other sentences where both "have to"and "must" were accepted as a translation for πρέπει. In English the two are synonymous, even if must is more colloquial
για το ''πρεπει'' ποτε βαζουμε ''have to ''ποτε ''must'' και ποτε ''need''
Πρέπει να πληρώσω το αυτοκίνητο σήμερα -- σωστό?
