jxk -- So far as the vibration and low static RPM problems are concerned, yes. There were many other unpleasant surprises with the aircraft, almost as reprehensible (and even more expensive), that surfaced only when I instructed my mechanic not to believe a word the log-books said but to verify everything with his own eyes. The authorities are looking into some of those too. Suffice it to say that the pre-purchase inspection I commissioned was a complete waste of time and money.
