My mate Adam does all finance and salary packaging at Salpac. You'll be able to pay for the car with pre-tax dollars if you set it up correctly. It'll save you a tonne of cash in the long run.
Ask him to explain the different types of finance like Commercial Hire Purchase, Chattel, Spouse, Associated, Novated, and he'll suggest whats best for you. Say you know Darren though the 370 forums.
