Your company is considering purchasing a used dozer for $180,000 that she could use for ten years and then sell for an estimated salvage value of $10,000. Annual maintenance and repair costs for the used dozer are estimated to be $15,000 per year. As an alternative, the contractor could lease a similar dozer for $4,000 per month. Should the company purchase the used dozer or lease the dozer from an equipment dealer? Annual operating costs are approximately the same for both alternatives. Use a minimum attractive rate of return of 12%.
