rollover plan

If Beethoven had been a Zipcar member (yeah, we know that's not possible) and he chose a plan with rollover, he wouldn't have to worry about using up all his driving credits during the month. Let's say Beethoven was a high roller and he was on the EVP $250. And at the end of the month he'd only used up $200 of his $250. No problem, the remaining $50 would be automatically rolled over to the next billing period (and even the next, if necessary).

Some plans have one month rollover and so unused driving credit can be rolled over to the end of the next billing period. Other plans have a two month rollover and yep, you guessed it, the unused driving credit can be rolled over to the end of the next two billing periods.
