Mark :
Look at the overall picture of the plane . I agree fully with comments on damage history . I would tend to focus on the engine . Date of overhaul , what TYPE of overhaul , Any recent prolonged down time . was it flown on a fairly regular basis . SMOH hours . OH yes and do check each engine log and make sure that the engine data plate agrees with all the logbook serial numbers and if not why not . For the most part , the engine condition / history is the achilles heal of these birds so if you know what you are dealing with under the hood you have half the battle won . Nothing is going to be " perfect " its a judgement call . you just want as many facts on your side to be able to make it .
