Local car lot has an 04 STi for sale with 104,000 miles on it. One of my mechanically inclined friends is interested in it and took it for a test drive. He said the car is solid except for a little noise being made by the right rear strut. Sticker price is 15,999 but the dealer said he would sell it for 15,000. Is that a nice price? What would be a nice price? Please convince me not to buy it.
