Poodroo, I'm fortunate that me ute is a business expense. So I can claim the repayments and the depreciation as a tax deduction. On the other hand, I start losing money on a ute if I keep it for more than about 6 - 7 years as it has depreciated too much to claim.
My wifes car is a different matter. We are in the same boat there. Luckily for me she can't see the point of buying a brand new car and throwing away the GST and other on road costs. They are what make buying a new car rediculously expensive. So she is happy with a car a couple of years old.
Problem is, the money ww save on on roads and depreciation for those couple of years, I now have to spend on getting her a better used car!!
