Re point (1) - NOT SO !!
This is a very sore point with me: in Spain the most common fuel policy is Full-Empty, i.e. you pay at collection for a FULL TANK, not at pump prices but at whatever the company charges, and then you are supposed to return it EMPTY. However it really doesn't matter to the car-hire company whether it is empty or not because you've paid for it all anyway. There are no refunds for returning it 3/4 full and this practice is a blatant RIP-OFF!
We need a car for usually no more than 1 week, we do very little mileage and we barely use 1/4 of a tank. And yet we, and presumably everyone else, are required to pay 60 euros up front for FUEL WE DO NOT USE. The car hire companies are ripping us all off because, let's face it, unless you are doing a very high mileage, the tank is never empty on return.
I cannot believe that this situation has arisen. I've never come across it anywhere else and have hired cars in a number of countries - the standard policy was and is FULL-FULL which is perfectively fair: you pay for what you use and at pump prices. But not in Spain now - you pay whether you use it or not and, at an extra 60 euros usually on a 120 euro hire cost, it amounts to a huge additional cost if you don't use it.
There is only one company we know of, Record Rent a Car, who does not operate this rip-off. They are represented at Alicante Airport but not at Murcia where it seems there is no choice whatever: ALL the car-hire companies at Murcia charge on a Full-Empty basis.
And I just cannot bring myself to accept this. There should be more customer resistance to this dishonest policy - our lone battle is unlikely to alter very much.
And if anyone knows of any other honest car-hire companies in Spain, especially at Murcia, I would be very glad to hear of them.
