Based on the median U.S. income, it could take literally years expecting no additional discretionary income to come up with that kind of cash, or even longer if individuals are trying to keep cash reserves to situations like one we're currently experiencing. In practice. owning a car as an asset it generally considered a positive versus alternatives like leasing, which results in the accumulation of no vehicle equity over time.
There's not really a great solution here. Cars are capital assets--they're complicated to build yet already somewhat commoditized in their pricing. They can also last for much longer than most other consumables assuming reasonable use. With regular maintenance, I don't think it's unreasonable to assume well over 10 years of use from most modern vehicles, with most automotive loans having a shorter period. I'm not sure I can think of another commonly-used product that closely matches those conditions...
