The car is nearing the end of its life, so the options are to either overhaul the car or replace it with a new car. D&M’s has put together the following budgetary items:

If D&M replaces the transmission of the pizza delivery vehicle, they expect to be able to use the vehicle for another 5 years. If they purchase a new vehicle, they will sell the existing one and use the new vehicle for 5 years and then trade it in for another new pizza delivery vehicle. If they trade for the new delivery vehicle, their operating expenses will decrease because the new vehicle is more gas efficient. This project is analyzed using a discount rate of 15%.
