There is a cost of not using the 1000$ bike in place of the 275$ bike. This cost is related to your needs and the fact that you have already paid for the 1000$ bike. Both bike would answer your immediate needs (going from A to B). But the 275$ bike would not answer some secondary needs (satisfaction, wow effect, speed, reliability, effort, ergonomy etc...).
If we suppose the 275$ bike answer 50% of your global needs and the 1000$ bike 95%. Plus the fact that your 1000$ bike depreciate with time. Then here is the hidden cost.
