I'm brand new on the forum, but I've been wanting a crossfire since I was 14. I'm interested in buying this one, my only concern is on the Auto Check report on ebay, it lists a odometer reading of 31,600 in 2009, and a reading of 1000 miles less than that 4 years later, with a note that the reading wasn't included in the odometer check. Should I be concerned about a rollback on that?
