If you not sure about tenure here you are far better to rent until you are, I brought a new Calais in Aust, cost me about 40K, sold it 8 months later for 25k Ouch.
You will find small car rental places, many with only 2 /3 cars pickups who will rent on a monthly basis 4 drs for about 15K PM.
There is one around the corner for us, they rent near new Colorado's and Mitsui pickups.
