Sounds like a good deal. I paid $23K for mine, it had 65K at the time. Check the seats. Mine go "clunk" when my body weight shifts like when going around a corner. I believe the seat frame is broken on mine, a common problem. I don't know if anyone has come up with a good repair yet.
M.B DOC, what do you mean by auto trans 722.6? Is that the type of transmission? Are you saying that the sealed transmission should be serviced by 85K miles?
