if your in Qatar you will need to have a local bank account for ur salary to be transfered to. I'm not sure about this but i dont see why u cant pay cash and buy the car if you have it? but opening an account here is a must for salary transfer..if your going to buy a car by taking a loan then the car company will give u a quote and u have to show that to the bank to get a car loan.
