Every dealer knows the number a new car loses the day it is titled, because they see it from the other side: the trade-in of a 14-month-old car with 11,000 miles that was $34,000 out the door and is now worth $25,000 at auction. The buyer paid $9,000 to own a new car for a year. Sometimes that is a fair price for what they wanted. It is almost never what they thought they were paying.

This guide walks the depreciation curve with one example car so you can see where the money goes, and then shows the three cases where new still wins. Every figure is illustrative; your model, your market and the rate environment move them.
