Knowing how much something actually costs is super important, because it lets you balance that things value to yourself against other things.
Insurance, maintenance both regular and semi-unexpected, registration, gas, replacement, parking. It all adds up. (And skimping on maintance tends to be a loan from future you with a loan-shark interest rate, sometimes including the busted kneecaps)
As I relish being the colossal nerd I happen to be, I love working these things out myself. Even if you don’t, you can get a lot of value roughing the numbers, and there’s plenty of tools out there that can help.
So ya: anything big you use, it’s probably worth it to figure out what it costs you in a way you can process and compare in your gut!
As well as the banal but important “i know how much i can spend on recreation and not get wrecked by credit card debt when i have to buy new tires”.
