Hello everybody and thank you for the answers! 

Well that is very interesting but I have another question: How about if I am being hired by a german company and I go to work for them down there?  Salary should still be the same?

And from what I have been reading it is standard to work out a contract with housing, car and utility costs listed separate.

So basically in the contract there should be a "line" with

x amount for car

x amount for housing and utilities

x amount salary 

Kind regards,

David
