the story has a good point, but the example is weak.

if you're willing to pay for a ferrari, one would think you'd be willing to buy a regular parking spot for it.

and why would you drive it to the airport in the first place if you're planning on going out of town for a couple weeks? why not get a ride from a millionaire friend in their ferrari?

i'm not a millionaire, but it seems like being a good planner is at least as important as being a penny-pincher if you want to make serious money.
