Nothing a little TLC couldn't fix and be ready to fly.
I watched a 60 minute show on airplanes in boneyards. Every part stripped and sold is put into record. The show also said you can't just go buy an airplane from an airplane dealer or individual. I believe it said all airplane sales go through one central records base so that all airplanes are accounted for.
I watched a Pawn shop show that a guy wanted to sell a jet to the pawn shop. The pawn shop had a fighter jet pilot test fly the plane. He said the plane was good to go. The pilot told the pawn shop that the plane was worth around $150,000 but it also would cost about $5000 a month for storage, maintenance and mandatory flying time. The pawn shop passed on it.
