Have found what appear to be a few decent deals on 235's from the 60's on the usual sources. Decent deals meaning a 235 for the price of a comparable 4 cylinder Cherokee. What's the scoop on these? How much faster in the real world than the 180? They seem to be fixed pitch props in that vintage. Similar flying qualities? Maintenance hogs? Basically it seems to be a "If it seems too good to be true" scenario to get that much more plane for similar money, so I'm guessing there's a gotcha.
