Our Verdict

For most European road trips, DiscoverCars offers the best combination of price, insurance transparency, and cancellation flexibility. If you need the widest possible selection (especially in Eastern Europe), RentalCars.com is the safe choice. Budget travelers should check Economybookings first — their economy car prices are hard to beat. And if cancellation flexibility is your top priority, AutoEurope has the most generous policy in the industry.
