Hope they chucked in a tarmacing machine, the 60 uses runway like it is going out of fashion. Every time I see one taxi by or park next to it, I am amazed by the shopping trolley wheels. It has a nice cabin, just too bad you can't really go anywhere, especially when it is raining.
They are cheap to buy, less then half of a comparable airframe, there is a reason for that. Like everything else in life, you get what you pay for.
Buyers of used 60's buy them on price and price alone, if you were looking for an allround halfway decent cabin sized aircraft, any digging into the 60 would quickly discount it as a choice.
If you or whoever is consulting you on the purchase process would look a bit deeper then the pretty pictures you find on the web, you would quickly find its shortcomings, run a mile and go shop for a decent airframe.
