Rent a car for 1500-2000QR/mo for the first couple of months. Driving here is not Canada. If you're going to have an accident, it will be soon in your time here and make it at the car rental company's expense. Negotiating police, insurance and repairs is not a headache you need from the start. Once you're more comfortable about how the game works, you can figure out what sort of vehicle you really want and negotiate a good price.
