ZN - It is indeed a tantalising aircraft to consider as a possible private transport. Since you asked your question yesterday, I've been looking in some French aviation forums and it would seem you are not unique in your desire to own one..
However, as it is still an operational aircraft I think they dump the old ones - there is a "graveyard" of them at Chateaubernard.
I don't know if you ever visit France but the French are reasonably open about their airfields and operations and they do public visits around the Squadron at Cognac. There are also a number of articles about people winning competitions (one from a supermarket!)and getting a flight.
You can also visit the airfield museum - a link here showing a tour with a glimpse of that Flat 6 at the bottom and a rather nice air-to-air pic if you scroll down a bit
