this is interesting actually.
because a physical asset like a car might *look different, as cash might be physically different.
but unlike cash, which is usually accepted at the same value regardless of physical appearance, a busted up car isn't worth the same amount.
otoh the car might have *reputation attached to it, like an accident on its history report. this is similar to a UTXO coming from a questionable " high risk" address.
so we probably should see fungibility as a function of market forces, and not something intrinsic to the asset itself.
I don't know about Honda civics, but generally reliable cars like this are probably considered *more fungible* than other make/models that are more prone to failure and have high maintenance costs.
but at the end of the day, since the value of Bitcoin UTXOs are sometimes compromised based on reputation, it's obvious that they have *very delicate* fungibility due to bitcoins transparency.
