Huh? You paid X dollars a long time ago for the Honda. If instead you and your identical neighbors had been sharing a sequence of Hondas which were driven continuously and then replaced, your contribution to the purchase prices (i.e., the total price of all those cars divided by the number of neighbors) would have been less than X dollars (since your Honda is still running). Furthermore, it would have been spread out in payments over 14 years rather than being paid upfront in 2003. Therefore, you could have kept that money in the bank stock market earning interest.

That's the cost I'm talking about. The maintenance cost of raw sitting time (rust, freeze-thaw cycles, etc.) are additional.
