While it sounds good, an often forgotten fact always gets left out of the equation and that is the psychology of diminishing returns. Yes the bike cost the same however with most situations the “newness” at some point diminishes.
With a single payment, it’s over and done. You hear it all the time when the luster wears off “yep and I’m still making payments”.
On the other hand, doing the monthly thing allows you to keep cash reserves for something you need need or an opportunity should one arise.
This situation is a rare exception however as most Americans don’t have the cash so financing is necessary. Personally, my companies pay cash for everything and I write it off. I do lease one of our cars but I pay the entire lease for the term up front so I don’t see an invoice. On a bad day when I rant about not needing the thing, at least I’m not staring at that invoice every month as a constant reminder of buyers remorse.
on an off topic but relevant in the scheme of things, financing back in the day was almost exclusive to real estate of business infrastructure.
Today you can finance a can of soda. The ability to purchase what you don’t have the ability to pay for is why the overwhelming majority of Americans are broke. Most Americans don’t own the clothes on their back, the bank does. Slaves to the very end.
