Before I got a vertical, I'd have been all over that. IMO, it's a steal at $750 assuming it's in good, running shape. Run, don't walk. Hell, if it were local I might be all over it today. A lot depends on location - some places seem to have an endless selection of premium 'old iron' to choose from. I've never lived in any of those places... In my experience, that's a sweet deal unless the owner is hiding some giant flaw.
