Hi All,
       I've used most companies at Reus airport over the years and most do a full/full policy but only for hires 3 days or under so the siphon method is the best if you're not going to use it all, keep it for your genny. The only problem I had was when I took a "fuel refund" offer from Goldcar last year where the hire was for 2 days and they return the money to your card for each 1/8 tank unused. They took their time and only for I had taken a picture of the fuel guage I would have had a tough time I suspect. That said we're out again over Easter and using a different company so we'll see how that goes. :) I've toyed with the idea of buying a car and leaving it out there but when you do the sums and add in the red tape its not worth it for 5 weeks a year, you'd need to be coming out regularly for longish, month or so visits to make it pay. I know Irish people who leave Irish reg cars out here and take a chance with no N.C.T. OR m.o.t. cert but if you have a prang your insurance won't pay out cos the car isn't roadworthy and then the sh!te hits the fan.
