Taxes - I think you are required to pay income taxes here, but coming from Germany that would only be beneficial to you. Income tax is much lower. I know a few people here where the company also pays for the telephone connection and airconditioning costs - if the airconditioning runs day and night it can be quite expensive. We use fans, not because of the finances, but because we like it much better than living in a fridge. How about home leave tickets - normally they provide one a year.
Cars are very expensive, but taxis are very cheap compared to Europe.
