How many miles should an odometer read for a 2008 car in 2015?

The answer depends on how much the car has been driven since 2008. Generally speaking, if the car has been driven an average of 12,000 miles per year since 2008, the odometer should read around 84,000 miles in 2015. This is calculated by multiplying the number of years since 2008 (7 years) by the average annual mileage (12,000 miles). However, the actual mileage may vary depending on the individual driving habits and usage of the car.
