Everybody seems to say "run". I think a lot depends on how much you are to do any of the work that might be necessary. If you're the kind who has to call an electrician to change a light bulb then "run" might be the answer. However, if you are able to rebuild a totaled DC3 then "run" might not be the appropriate thing to do.
Depends on your skill levels, desire to invest the time to repair if needed and determining if there is even a problem in the first place.
I don't know you. Maybe others do. At any rate, if there is in fact some long standing delam then there may be a bit of work to do. If you get it at the right price it may still be worth it.
