Top 7 best websites for car rentals (for leisure and business travel)

Whether you’re about to book a road trip across America, a six-week trip to Europe, or a weekend away in Canada, renting a car can be a cheap and convenient way to explore your destination at your own pace. 

That said, combing through the choices that come up during the car rental search process can be a bit overwhelming—Does the final price include car rental insurance? Can you return the rental car at a different location to where you picked it up? 

Before you hit the road, we’ll sift through the details and frequently asked questions to break down the best car rental booking sites for both business and leisure travel.

To help you make the best choice and better compare the best car rental companies, we searched each site for a 3-day midweek car rental in New York for dates two weeks out from the time of writing. We’ve included comparison details for these searches within each section.

Ready? Then fasten your seatbelts and let’s dive into the details to help you book the best car rental for your next trip.

Wrapping up the best websites for car rentals

The seven car rental websites on this list are a great place to start if you’re looking for a reliable car rental service for your next trip.

It’s worth highlighting that we intentionally excluded travel aggregator websites like Expedia, Kayak, and Booking.com from our lineup. While these aggregators cover a broad range of travel options—including flights, car rentals, and accommodation—they might not fully satisfy your particular car rental preferences, offer the best perks, or give you access to loyalty programs.

Opting for dedicated car rental platforms provides you with a more personalized and efficient experience that’s more customized to your specific travel requirements. Whether you’re gearing up for a leisurely vacation or a busy work trip, these dedicated car rental websites offer the tools to ensure you’ll enjoy a smoother, more personalized journey.
