Hope your right mate, after Holden and their "Monaro" stuffed the 24hr, as you say this could become a great international event.
The thing with the Monaro was that it was a GT car running around with production cars. I was opposed to it then, but if they want to bring them back now that there is some fair competition, be my guest, we may even see that they really were'nt that good.
If the organisers of this event spend some money and play their cards right, I can see teams from Europe and the US bringing their cars over here. I just don't know about 12hrs, may have to make it a 24hr race to make it worth while to make the effort.
This event could be another Spa, Nurburgring, or Daytona 24hr race. LeMans? I think that event may always stand alone.
