In an ideal world, you should book a rental car as far in advance as possible. The earlier you book, the more time AutoSlash has to track your car rental reservation and watch for an even better deal.
But sometimes you just can't book in advance. Maybe you have a last-minute business trip or a family emergency. Perhaps you are taking a spontaneous weekend getaway, or your flight gets cancelled and you decide to drive instead. Whatever the reason, sometimes you need a car at the last minute.
