Don't use Carjet.com They work with local rental offices and DO NOT check if these are reliable ones. We just had the most horrible experience with Carjet renting a car from Right Cars / Apollo car rental in Athens airport. They try to set you out with a worn out car and upon arrival they tried to rip off money for a minor scratch made by us. We didn't. As a matter of fact, the whole cars had these minor scratches. We let the police come so they let us go. They didn't want to give the damage report of €300 because I didn't want to sign. Now they withdrew €995 of my creditcard with a damage report signed by a different person. Carjet must have known this, because now we are checking the reviews and all of them are bad for that particular local company! So Carjet does NOT look out for you!! And DO NOT rent from Right Cars / Apollo Rent Athens.
