Goldcar in Palma de Mallorca are total crooks.
Not only do they charge you €108 for a tank of fuel for a B-class car, it is non-refundable and you can't return the car full to avoid this charge.
They are also the rudest people I have ever come across. Make sure you do not sign anything (including one of those digital sign systems) until you have seen fully the terms and conditions as they get you to sign and then apply your signature to the fuel agreement before you have read it.
In fact never ever use them, they deserve to go bust.Edited: 25 July 2011, 10:30
