You are considering a purchase of a new luxury automobile at a cost of $175,000. By being a luxury taxi driver, you expect the vehicle to generate average revenues of $5,000 per month. Average operating costs will be $1,000 per month and there is an annual oil service that will cost $3,000. You expect to keep the vehicle for 10 years at which time it should sell for $60,000. Determine the internal rate of return if this investment is compounded annually. If your MARR is 6%, is this an acceptable purchase?
