just a note of warning for the expat community not to consider Alfa Relocations (including their agents for Spain Amygo) for your possible move.
The company comes accross as the ceapest, but that has a serious effect on their service too.
We had the nasty experience that they messed our move, got a list of items broken and lost crucial papers to legalise our vehicles.
The worst thing being that they decided to ignore the situation which they could still have recovered it.
On the contrary, GAC is very professional and recommendable.
