Rick, when he wаs 16 yeаrs оld, bоught а used car frоm Car World for $7,000.  He drove the car for a year and put 15,000 miles on the odometer.  He was also involved in a minor accident.              At age 17, he wants to disaffirm the contract with Car World and get a full $7,000 refund.  Car World objects.  Its owner says, “Look, the car has higher miles that it did last year, and even if it wasn’t damaged from the wreck, I could only sell it for $5,000.  And with the damage on top of the higher miles, I can’t sell it for more than $3,000.  And besides, I sold this car more than a year ago – I shouldn’t have to issue any refund at all.”             What refund should Rick receive if a court applies the rule that is applicable in most states?
