Hi Ritarabag. Am I to understand that if I bring my goods from Uk to Spain in my van I am doing something illegal once I cross the Spanish border.??

If your van is registered in the UK and has an MOT and insurance then you are OK the problem arises when you are a resident of Spain and using a UK motor vehicle. When you first arrive you have 6 months to get the van on Spanish plates I think if you are already living here its 30 days. You also have informed the DVLA that your UK vehicle is a permanent export you will need that UK paperwork when the Spanish engineer inspects your vehicle  re head lights reverse lights etc, Prior to the ITV test and change of plates.. The form numbers are on the DVLA web site.

If you are taking your car or van to the ITV station the is a good blog below that gives you a bit of an incite and some lingo tips the ITV tester may ask of you. Its worth a read and the comments afterwards are worth noting..
