The employer had purchased the car the day before for $30, 000. Joe used the car solely for his personal use throughout the year. The annual rental fee for such a car is $5, 000. If Joe has additional compensation income, that amount will be:

B. $5, 000
C. $25, 000
D. $5, 000 * number of years Joe is allowed to use the car
