Basically, If you are a Spanish resident, you are not allowed to drive a UK or any other foreign vehicle.
If you are no resident you are allowed to have a UK car in Spain for 6months (183 days) and after that, you will be considered a tax resident and so are NOT allowed any further use of UK vehicle.
The reason for my original post was that maybe we will see a very big tightening of the rules if a no deal WTO Brexit occurs. I was told by a fairly large garage owner, that the motor trade are on standby for a glut of used UK cars stuck in Spain coming to the open market. Transporter companies could also be rubbing their hands.
May be if any of us have just been running UK cars willy nilly, now is the time to get rid and/or get legal? I'm not scaremongering peeps, just some thoughts.
BUT maybe the Spanish will just shrug their shoulders and carry on, as it may cause some Brits to take their money elswhere ???
Quote from the website
"Nonresident can drive and keep a non-Spanish plated car here for up to six months in any period of 12 months. This is tied in with the residency issue as you are considered a resident when you reside here for the same amount of time. Link with the EU Directive that states this. art. 3"
