Pick a well known/ typical bought car model (Ford Fusion Base $21,495) and plot depreciation (2,000 per year) for at least ten years normalizing as needed, etc., for model changes and adjust for inflation (2.07%) as needed. Also plot on the same plot the path of the depreciation model that best fits the actual curve. Plot expected maintenance costs and reliability over a ten-year life assuming 20,000 miles for year. Add S100 per lost day for a rental car. Make clear your analysis of surprise, lost use "political" considerations assuming this is your only car.
