Don't buy this airplane. As Dennis O'Connor has itemized, the bills
will go on and on and you will run out of money before you ever fly
it.
Find another airplane that some poor guy has already made the
same mistake with; one on which he has already spent a fortune fixing
everything, and from which he can't hope to recoup the cost. You'll
have a nice airplane at half what that Aztec would cost you.
