All depends on your total package. If accommodation is provided you should be ok, as long as you don't live beyond your means, as many expats do here. There the ones who bail when they realize that the nice new car, nanny, maid and fancy restaurants actually need to be paid for. As Miklo says, if accom is provided, you need to know where so you can enquire about the area, quality of housing and indeed the neighbours.

You can get a Suzuki Swift for around 1700QR per month if you rent for 6 months or more, or a Chevrolet Epica for 1800QR.
