AVOID! AVOID! AVOID!
They will coerce you to take out their full insurance cover, if you don't then they will clutch at straws in order to keep a good part the 1200 euros insurance premium. As they told us, if a small stone hits the car and leaves a mark they will keep 600 euros!
Also when you book a car they never say what engine size it is going to be. I specifically booked the open corsa "type" thinking it will be at least 1.2 and when I got to the airport they said I booked a 1cc car!
Scammers!
