I'm baffled by the thought of a seized /6. I know they'll stop if they get hot, but let them cool off and they'll usually restart. My in-laws killed one in a Volare after they didn't change or check the oil for 18 months or so, but the only reason it wouldn't start was #6 rod escaped and broke the starter off of the bellhousing...

Looks like a great buy at that price.
