I'm looking to buy a late 70s/early 80s Seneca within the next couple months. I've found plenty of good ones on Controller and Trade-a-Plane, but I thought I'd post here and see if anyone knew of any airplanes off the regular channels that might be of interest. Also, any Seneca owners out there know of any "gotchas" when it comes to these model years? Anything in particular I should check for aside from the normal stuff (ADs, SBs, corrosion, etc.)?
