I am partially with Landflap: order now, you may always cancel or resell the plane.
Secondly there is a lot of old aircraft that is past needing replacement...
And there is the local market, Iran is a big country and even an a380 might be filled on some national routes. The a380 will certainly come in handy for hajj charters to Mecca.
Add some smaller planes for routes to Asia and Europe for both the local market and people with destination Iran (an oil producing country...)
