4. Kayak: Best Car Rental Search Site
Unlike Expedia, Kayak is a metasearch engine that searches major car rental companies, online travel agencies, and local rental locations to show you options and prices for car rentals.
That means you can’t book a car directly through Kayak and have to go off-site to specific rental car websites to make your payment and reservation. While this isn’t as convenient, it does mean Kayak isn’t limited to searching rental car companies that work with them directly, so you get a much wider range of options (and often better prices as a result).

Within the search results for Kayak, you’ll see options to book rental cars directly from rental car companies, through online travel agency sites, or even from car-sharing sites like Turo.
One other downside is that there is no option to purchase rental car insurance online through Kayak. Again, you’ll have to do that through whatever provider you choose from their list.
If you’re looking to find deals for your entire trip, Kayak also lets you search flights and hotels. I’ve had good luck finding inexpensive flights through Kayak, so it’s worth checking out!
