Id take sinbads advice mate, wait for Sarah to move in and leave it for a couple of months, see how cash flow is then, then once everything pans out look at getting a sensible car with a bit of power, me personally in your situation Id get a Golf TDI, it may be deisel but one chip and you will have more torque than the Z, then enjoy modding it yet save buddles on petrol and still have speed !!!
