Of course you do!  The people Blue Donut have invented a formula to determine how old your car is in people-years.

Take the mileage on the car's odometer and divide by the model year. The result is your car's age if it were a person.

Example: a 1994 Chevrolet Cavalier with 131,824 miles on it. Do the math:
131,824/1994 = 66.1.
That car would be a 66-year-old person.
