The V de V site was down at the end of last week, which is no doubt why my searches drew a blank. Well it's back up and they are holding a 6 hour historic race at Estoril on 21 - 23 November 2008. see:

Since this circuit is only 300km from the Algarve circuit where the Masters are proposing to run a meeting just the week before, it could make a nice jaunt in the sun.
Anybody thinking of going for the double?
