This is a classic example of a scam that is going around. It is especially targeted at airplanes, collectable tractors, and collectable autos.
The English is poor and it is not well written. They want you to send money to someone out of the country so they can come to inspect the airplane.
I would not even bother to reply to a message like this one, it is a waste of your time.
I'm seeing this same scan described on the ytmag.com discussion board (yesterdays tractors magazine).
