Before I list my wish there is something to consider, a lot of us fly with Virtual Ailines; some a lot, and others from time to time.  If you look there are very few that fly nastalgia type planes. Do not misunderstand, I like the old, that is right now why the CS727 is getting all my attention.  For CS to stay in the green they have to balance new and old, so even though a Convair would be cool, it would turn into to one of those planes that you would fly seldom versus flying a B737-800.  My vote in order:


B737-300/500 was a classic and was when digital invaded the analog cockpit.  By far one of the most widely used versions.  This to me (then they could add like the 757/767 addon like a B737-700 and 800)

A380 - Not one out there that is quality!
