Option 1 – No Finance
Your first option is, of course, no finance at all. You pay for your current car's running costs using the cash you're paid as a car allowance. You will enjoy the flexibility to spend it how you wish, but the entire allowance is still treated as taxable income.
Option 2 – Commercial Finance
Many employees who get a car allowance will qualify for a chattel mortgage finance product. If most of your driving is done for business purposes, and you meet the application requirements, a chattel mortgage will typically offer you a better deal and more flexibility than other consumer loan products.
Alternatively, you may be eligible to apply for a car lease. While there's no option for trade in or deposits, and you should be aware of the fixed minimum residual values set by the ATO, this option gives you the flexibility to either payout the residual at the end of the term, or upgrade to a newer vehicle.
Option 3 – Consumer Loans
If you're not eligible for a commercial finance option, the other popular option is, of course, a car loan or secured personal loan. By using the car you're buying as security for the loan, you can lock in a great rate, but you won't be able to borrow above the value of the car you're buying.
If you have a home loan, you could use equity in your mortgage to buy a car. While this will typically offer you a low rate, unless you pay the extra borrowings off quickly, you may end up paying a very high amount of extra interest over the life of the loan – far higher than you'd pay with a typical three to five year car loan.
Option 4 – Novated Leasing (and salary packaging)
As an individual employee, your employer may offer you the option to forego a car allowance in favour of a novated lease, also known as salary packaging or salary sacrificing. Novated leasing allows you to pay for your car (and, in the case of a Fully Maintained Novated Lease, your operating costs) with your pre-tax income. A novated lease can save you GST and income tax, but it also gives you the convenience of a simple regular payment that covers all the expenses of owning and running your car.
