Should I get an old 337?

I'll also recommend spending the extra money up front. I just went through this process. After I purchased my Skymaster I had over 300 hrs. of labor invested into it. Then add in the cost of boost pumps, fuel quantity transmitters, fuel cap upgrades, alternator repair, magneto inspections, engine hoses, hydraulic hoses, seat belts, the list can go on and on, it can get very expensive.

Then, chances are these also need to be done. Interior, say 3000.00-4000.00, paint 12000-15000, engines approx. 30000-35000 ea., props, if they can be overhauled, around 2200 ea., avionics limitless. These are all ballpark figures, but I think they are reasonable.

Add these up and it easy to see your better off to buy one that's turn key.
