I don't expect that to be financially viable too long into the future. Once a significant enough portion of the general public's fleet turns over you can expect to see onerous requirements applied to older vehicles to get people at the margins to buy newer stuff (e.g. inspection programs that drive up the cost of ownership under the guise of safety, some states already have these). Insurance lobby wants people in new cars. The Karens don't like seeing old junk. The upper middle class wants everyone driving EVs for the planet's sake. The state wants to be able to track everything. None of these parties care that most of the people affected will have credit scores in the 400s and be forced to do business with predatory "buy here pay here" lots.
