I pretty much understand the difference between operational costs and other costs. 

Everything you listed about a car is an operational cost except the purchase cost.  I do understand that if you fill your car with gas and it costs $20, and you only have $10 then you have a $10 deficit.  That would be a $10 operational loss to someone if they had to make up the difference for you.

Let's say you bought a classic car and park it in the garage where it sits and you don't operate the vehicle.  You paid $30,000 for the vehicle and you now begin to depreciate it at annually at $5,000 for the next 6 years and you consider that $5,000 each year as a loss.  You keep the vehicle for 12 years and sell it for $$40,000.   Have you really lost any money on the vehicle?
