Moving to Rio

Hi Pablo!

I'm from Rio, living now in London.  Rio is very nice to you if you earn in foreign currency.  Food is a lot cheaper than abroad, but eletronics in general are much more expensive.  You should consider bringing the best laptop with you, unlocked blackberry, maybe a tv - if you are into it.  Remember to always have insurance over anything you have, robberies are quite comom, unfortunately.
As for a car, in Brasil you get much less for your money.  The cheapest brand new car will be around 15K dolars, and that means no frills, not even an air condicioning.  Prices drop dramatically from a brand new one and a few months old one.  It all depends on what is important for you in a car.  Remember you can't survive without air-conditioning, as you should not open your windows when stop at traffic lights...
