I'm intending to live out there for up to 3 months possibly more using my sons place as a base whilst we look around at areas we may want to settle down in, as we are looking to live there permanently when we decide which part we want to settle down in, my income will be from my business in the uk, so do I need to bother with a residency cert. or should i become a resident even though i am not yet permanently living there, also i believe i cant buy a car in spain if i am not a resident is that true if so what is the best way of having a car to use whilst i am there. any help is appreciated.
