I asked the same question of the prior owner (they had it at their school in WI and then FL)and their A&P/IA. They said the same thing. That's why I spent the money (commercial flight, hotel, etc.) for my A&P and I to fly to FL and look at the plane. I won't say anyone is not being honest/truthful. I will only reiterate that I have not seen that much corrosion in a flying aircraft. Perhaps they look at things differently in FL. I did subsequently buy an Aerobat, and am very happy with the plane. I had that seller take nice, bright pictures inside all the inspection covers prior to flying to inspect that plane. It paid off.
