My friend bought his 95' polaris indy trail with 8,500 miles on it...and I know people who've bought sleds with over 12,000 miles on them and they've all been running fine. Like I said maintenance, overall condition, and good compression is the key to a good sled! I wouldn't worry about the miles on that sled one bit if those conditions are met!
