I'd be working out the numbers before deciding to purchase a car within a business (assuming you are running a business). Due to the associated Fringe Benefits Tax Conseqences
As going off rough calculation FBT Tax Payable on a Motor vehicle $125,000 using the Statutory method off 15,000km a year is approximately $31,000 in tax. You will also continue to pay FBT as long as a car is held in a business name.
There's other factors to take into account such as the GST refund you would get and depreciation depending on the type of lease.
But there are a lot of factors that make the numbers, so as such some situations it is beneficial and some others it is not.
