I'm told that you don't need to register mopeds in Spain but an internet search implies otherwise. I would like to buy a small 49cc moped as a runabout for 6 months over the winter and want to be fully legal. We both have full UK driving licences but don't own a car anywhere. We are not residents in Spain and don't have a NIE numbers. Our only addresses are home in the UK and the boat in the marina. Can anyone tell me how to go about it, please? We are in Andalucia.

Many thanks.
