Buying a bike in Spain should be easy . There are lots on offer , and at a reasonable price .
The paperwork, is mostly straightforward , and ASSUMING THAT THE BIKE 'got ITV valid(Spanish's roadworthyness test) , you can do all the paperwork in one morning .
You need : Carte Grise (gray card , which is the spanish doccument's for vehicle )
YOU NEED TO HAVE THIS DOCCUMENT SIGNED BY THE SELLER , aND THAT SIGN CONFIRMED IN A BANK . (that is , go with the seller to a bank , and have his sign checked there , should be free of charge) .
"Certificado Caracteristicas Tecnicas " , a greenish paper stating the weight , power , etc.. and the inspection log . MAKE SURE ITS GOT A ITV valid . OTherwise you can not transfeer the vehicle
With these 2 papers and A PHOTOCOPY OF THE SELLERS ' ID CARD ... you can register your bike in 2 -3 hours. The whole opperation costs 60 EUR + 4% of the agreed price (traditional to cheat on this and put a lesser ammount of money to dodge taxes , but dont go too far !!!!! ) .
If you need exact instructions , adress , assistance etc.. etc.. etc.. pls mail me .
