A used defender can be kept for two more years and then sold for an estimated $3,000 or it can be sold now for $10,000. The average annual maintenance cost over the past 7 years has been $500 per year. However, if the car is kept for two more years, that cost is expected to be $1,800 the first year and $2,000 the second year. As an alternative, a new challenger can be purchased for $22,000 and be used for four(4) years, after which it can be sold for $8,000. The new car will be under warranty for the first 4 years and no extra maintenance cost will be incurred during those years.

If the MARR is 15 percent per year what is the better option?
