Add to the list, at least possible failures in the near future, driveline bearings, boggies wheels, track, drive axle. I don't know, but I bought a 07 attak just 1 year ago for $5300.00. Had 6000 miles on it. Nothing was really wrong with it, but I have $2500 in maintainence repairs. Well for a couple grand more, I could of bought new.....or very close to new. I love my sled, and now I am so deep into it that I will keep it a few years, but I wish that I had just went with new, or at least much newer.
