All the jigs and associated tooling still exists?
If you look closely at the Malibu variants and the now shelved PiperJet its pretty clear where the fuselage has come from.
Its a pitty Piper went with the Seneca as their business twin. I would have thought the PA31-325 would be ideal for that market. It would only cost slightly more than the Seneca or Baron to purchase and operate and would be a brilliant machine with modern technology incorporated. This would keep the line open for replacement PA31-350 or the newer T-1020 or 1040 at a reasonable cost.
