Nigel is right,if you weigh up the cost of buying a car/4x4,cost of driving it over to Spain,cost of tax and insurance,cost of upkeep and repairs,depreciation etc,etc all for a few months use per year( assuming you don't  live there full time)and having it left lying around Reus airport for the remaining,surely hiring one would work out a lot cheaper.

P.S. Does anyone know if that is an airport parking firm on the road in,opposite the airfield ??? if so,it's a great idea,if not,it's still a great idea.
