3. Expedia: Best Car Rental Booking Site
Expedia is probably the most well-known name among online travel agencies. They’ve built a huge business around offering easy online searching and booking for hotels, flights, rental cars, and more.
If you want a streamlined, easy process for booking rental cars (plus find the best prices), Expedia has their booking process dialed-in. Unlike some other sites on this list that only search and track rental car prices, Expedia lets you pay for your rental car directly through their website. You can even pay for car rental insurance straight through Expedia.

If you are reserving your flights or hotels through Expedia, things get even better, since you can get a cheaper rental car by bundling your travel expenses together.
So what are the downsides? Well, Expedia doesn’t always find all the same discounts and coupons as you may get from other sites like AutoSlash, so you may not always find the lowest rental car costs.
