I am looking at the possibility of moving from Portugal, where
bureaucracy is a mad disease. I am interested to know what living in Spain is like. For example:

What steps, and how much time, are needed to import a used car into Spain and register it? Does the registration need to be renewed each year? Cost?

What steps are needed to get a driver's license,? what is the duration of
the license, and is a driving test needed at each renewal. I did Internet searches and found nothing useful.
Other bureaucracies?

I am also interested to know about life in the different areas of Spain, especially east of Barcelona to the French border, not too far from the coast, and in the west Andalucia area - possibly Cadiz or Huelva.

Thanks
julio
