Vehicles under $15k are 1.6% of the market, and their share of the market has dropped over 90% since 2019. The old advice that you can get a beater and drive it in to the ground for $5k hasn’t been true for years but it still seems pervasive in personal finance spaces.
Good point, I know you can find metrics on the average mileage cost of a car, including gas, maintenance, insurance, depreciation, etc. But I would be curious to see how those numbers fluctuate throughout the life of the vehicle. That is, what is the marginal cost of a mile, based on the already existing mileage. Based on the vehicle, you could plot the marginal mile cost structure, similar to how you would plot a yield curve.
