Selling aircraft

[skifans]

I'm not sure i understanding. Are you suggesting that when purchasing a used aircraft, 20% on the money goes to the seller as some sort of fee? (Presumably with the seller receiving 80%)? What exactly is the point of this, isn't the whole point of business to sell items for more then in cost to obtain them, i understanding that the use of such selling services probably isn't free, i am also happy to be corrected here but 20% seems quite high. I'm also not sure i understand what sort of "abuse" would be stopped, could you please elaborate on how the current system can be exploited?
