I work at a technical institution that teaches automotive technology and it really pisses my local Ford dealer off when I bring them the car and they say oh, we've never seen that problem before, then I hit em with the service bulletins from Alldata:hy: Its turned out to be a 17k pile of junk,its plagued with problems that Ford should have recalled instead of "service bulletins" issued.
