It responded with 686/year. I find that REALLY hard to believe...
You found it hard to believe because that was too high or too low?
Personally, I find airplane insurance for our birds surprisingly low. I remember, for example, thinking of buying a new Ford Mustang and pricing out insurance. Granted I was in my early 20's at the time but the quote was $5,000/year. For a $14,000 car. The insurance premiums cost more than the loan payments.
So when I asked for an insurance quote on an
airplane, I thought it would be outrageous. I mean, gee whiz, if a mere
car cost $5k/year, what must an
airplane cost?
About 1/10 the price.
So, from my perspective, airplane insurance is really cheap!
