John's 8 year-old Chevrolet Trail Blazer requires repairs estimated at $6,000 to make it roadworthy again. His wife, Sherry, suggested that he should buy a 5 year-old used Jeep Grand Cherokee instead for $6,000 cash. The disposal value of the Trail Blazer is $500. Sherry estimated the following costs for the two cars:

	Trail Blazer	Grand Cherokee
Acquisition Cost	$25,000	$6,000
Repairs	$6,000	0
Annual Operating Costs (Gas, Maintenance, Insurance)	$2,280	$2,100

1. What should John do? What are his savings in the first year? (HINT: Answer is Buy the Grand Cherokee; $680, but I need work to support this)
