Everyone knows that there are low season prices for most things that have to do with travel. Airline tickets tend to be lowest after the peak seasons which includes the winter holiday season and the summertime. Hotels are the same. Their rates are highest in the summer and during holidays when people are on vacation. Car rentals however are different. The best time to get a car rental bargain is generally very unpredictable.
The prices of car rentals tend to fluctuate from day to day and even from hour to hour. The best way to search for a car rental bargain is to do just that, search, search, and search some more. The nice thing about researching car rental prices as compared to airfare prices is that there is no penalty to make a reservation and then to cancel it at a later time. This is very different to searching for low airfares since the only way to secure the price is to pay for the ticket. The fact that you do not have to pay anything to make a car rental reservation and can cancel it acts a later time makes searching for car rental bargains a little easier than searching for bargains on hotels and air tickets.
When you find a rate that you think is reasonable book it but keep searching for other deals. The moral of the story is, keep searching for the best deal until the very last minute. You could save a substantial amount of money by doing this.
