Depending on the model & equipment, it's one of the few planes that can take fuel fuel, a bum in each seat & still have W&B to take some amount of baggage.
Nice amount of room for each seat. Even the rear row pax. sit bolt upright in a 'proper' seat. Compare that to the Barons, C310s etc where one's bum is only a few inches above the floor.
*Lots* of alternative gear extension methods. I often wonder if the bloke who designed the gear had a few gear-up related frights & swore "Never again...". Even if that all fails the gear can still support the a/c in the retracted position. Lose a few antennas, gear doors & possibly the props but at least you won't power sand the belly.
Wing section is the same as the Piper Cub. Enlarged a bit but still the same wing. Relatively docile handling as a result. Also good short field ability.
160kts TAS at ~130 Lph(?..been a fair few years since Iast flew one & that was a C or D model) (whatever that is in USG...) so abit fuel hungry for the
Biggest problem is a fairly narrow gap when the over wing door is open. The door travel is limited by the R engine nacelle.
Try to get one that has had the second hydraulic pump fitted. The original fit was one on one engine so you could have a nasty time of it if that was the donk that failed after take-off & the gear & flap was still out.
The only other thing I can think of off hand is the annoyance of the diagonal brace that blocks the baggage compartment from the cabin if you have a long, bulky item to carry.
