Yes, there are. As a small business I can accelerate depreciation deduction in the first year by a set value (5000). In the next year, it's going on 15% of it's book value. That is consistent with the redbook trade-in values which nearly all dealers use. The ATO will crack down on anyone who will report a much lower value in the books (for example the price for which I traded it in). A car hasn't used it useful end of life after being under 2 years in the books. I don't see this Astra being traded in for roughly 25.000 to 30.000 in 2 years time not considering what I have been offered over the weekend if I trade it in against another European brand car with a drive-away price of nearly 50.000 dollars. It's just 1 price that I got at 1 dealership but this is what they were willing to give at trade-in "considering the Opel situation and they would unlikely be able to sell the car to the public at a reasonable price... blah blah blah". Me just venting a little I guess but I hate to make a loss on money I work so hard for.
