Here are the best car rental and car sharing websites that I’ve come across in Spain. Some of them offer ridesharing too, which is a good alternative to traveling by bus, train or airplane.
With Amovens you can share rides with other people, rent cars from other individuals, or also put up your car for rent. The latter option will enable you to possibly pay off your car loan by renting out your car when you’re not using it yourself.
Socialcar is a ridesharing platform that also provides a buy-and-sell platform. They also offer motorhome rentals. Another cool thing they offer is to just leave your car in their car park and have them manage all the bookings and rentals for you. This is ideal if you use your car very infrequently or if you will be abroad for an extended period.
Blablacar is a great way to travel cheaply around Spain by sharing rides with other drivers. As a passenger you benefit from paying lower fares, and as a driver you can make money by taking on board passengers.
Bipi is a mobile app where you can rent cars. It is similar to car rental companies like Avis, Hertz etc, however the process of renting a car is much swifter as it’s done fully via the mobile app. No more waiting in queues at the rental car office. Bipi agents will bring the car to your door and you can also select a specific point in town for returning the car. It is a very comfortable service that is also cheaper than traditional rent a car companies.
