Thanks all for the advise,I dont live in Spain, and if the great day comes, and  I can afford to retire!!!!!! would prob only stay for six months a year, so would need something cheaper than hire car, what about a quad ?are they as complicated to buy and be legal ? the farmer below me, has a little ASP sorry if spelt wrong, one of those 3 wheeled trucks, So he also must only have a parcel number ?
I new this was going to be a difficult subject ! :-?
