10 sites to book rental cars online

Drive the price of your rental down by comparing the car rental companies from around the world.

Renting cars for holidays can be a confusing business. There are so many providers to choose from, all with different terms and conditistephaons, vehicles and models and, most crucially, prices.

We’ve rounded up the best car hire sites on the Internet to help take the stress out of your search.

What’s the difference between booking direct and booking with an online aggregator?

The first decision to make is whether you want to book direct through the rental company (such as Avis or Europcar) or through a booking engine or aggregator (like Expedia or Hotwire). We’ve previewed a mixture of both here, so you’ll have plenty to compare.

Something to keep in mind when deciding which to go for is the deals and specials each is offering. Sometimes it’s possible to get exclusive offers through aggregators, but going through an aggregator can occasionally create problems as it’s an extra ‘layer’ you have to go through if anything goes wrong. For example, if you need to change or modify your booking at a later date, you might have to contact the aggregator for details to contact the car hire company to make the amendments on your behalf.
If you’re going through an aggregator, read the terms and conditions properly so that you’re aware of who you will have to deal with at a later date and the processes to follow should any issues arise.
