Dakota Trucking Company (DTC) is evaluating a potential lease for a truck with a 4-year life that costs $40,000 and falls into the MACRS 3-year class. If the firm borrows and buys the truck, the loan rate would be 10%. The truck will be used for 4 years, at the end of which time it will be sold at an estimated residual value of $10,000. If DTC buys the truck, it would purchase a maintenance contract that costs $1,000 per year, payable at the end of each year. The lease terms call for a $10,000 lease payment (4 payments total) at the beginning of each year. DTC's tax rate is 40%. Should the firm lease or buy? (Note: MACRS rates for Years 1 to 4 are 0.33, 0.45, 0.15, and 0.07.)
