You can find some of the best car rental deals on the internet, but where do you look? Below we'll outline and review some of the best websites that offer broad car rental searches, comparisons between rental companies, and where to find the best car rental deals. Remember, when searching for an affordable car rental, sometimes rentals over 5 days work out to be a better deal than renting a vehicle for only a few days, so it may be more worthwhile to rent the car for an extra couple of days.

Orbitz.com - Orbitz.com offers a no nonsense, straight-forward car rental search engine that displays a grid pattern for your search results, comparing at least 5 rental companies and their prices. You are able to view rental prices based upon the class of car that you require (economy, compact, midsize, standard, SUV, mini-van, etc). We have used orbitz.com many times and have found them to be among the best for choice of cars, along with some of the best rates around.

Hotwire.com - Hotwire.com boasts "car rental deals that you won't find anywhere else", and most cases they are right. When you book a Hotwire Discount Rate rental, you're always guaranteed a car from one of the following companies; Avis, Enterprise, Budget, Europcar, Hertz, or National. However, when you choose to book the Discount Rate, you will not know what company you are renting from until after you confirm and purchase. If you prefer a non-discounted regular-rate rental, you'll be able to choose your rental agency by name during the reservation process.

Kayak.com - Offering instant car rental search results from over 80 companies, Kayak.com is a simple and effective car rental search engine. Lots of affordable deals can be found here, as their search engine searches all the large and small car rental companies, for both airport and non-terminal locations. A very useful search engine for car rentals.

CarRentals.com - Another very simple and easy car rental search engine to use, even going as far as to show you a picture of what your vehicle looks like in the search results. Airport or non-terminal locations are included within the search results. A currency option is also included in the search results, offering up the rental prices in over 35 major currencies, which makes it a lot easier when trying to calculate out exactly how much you are going to be paying.
