The average car is driven about 10,000 miles a year. This means that most cars have about 15 years worth of mileage. This fact allows us to combine mileage life and years of life into a single unit of measurement. In other words, a typical car has 15 year of life and 15 mileage units of 10,000 miles each. Thus, a brand new car has 30 units of life. As a car ages and is driven, these units are used up. If you divide the number of units left in a vehicle by its price, you have the cost per unit.
