I have several antique cars and motorcycles (drivers - nothing fancy). My wife and I differ on the "accounting".
I spent $3,000 this summer on another car (1951 Packard). She considers that a totally discretionary expense - and, if she wanted to, she should be free to spend $3,000 on clothes.
I consider the initial purchase a "capital asset" on our balance sheet. If later sold, the gain/loss is the expense/revenue on the "income statement". Obviously, tools, insurance, storage, fuel, etc are current expenses.
When finance discussions get testy, she brings up the initial purchase price of all the "toys" I bought over the years - cars, boats, motorcycles.
All the vehicles / boats I've sold I've gotten back near what I paid, some of the cars appreciated a little with restoration I did. So my net cost for the old car/boat/motorcycle hobby has to be near a wash for 20 years of playing....
She adds things up and says I spent well over $30,000......
