I have seen each of the Classics and in some ways prefer it to the 24hrs.
The delay with tickets is due to Peter Sport ,the organisers, the ACO are themselves ticket agents for this event. ACO members get 6 x 24hrs tickets at a discounted rate but only 4 for the Classic.
However I do not see tickets or camping spaces selling out spectator levels are 120,000 not the 222,000 seen at the 24hrs. Last year I bought 4 tickets at the gate as more mates decended on us than expected.
House full for next year and I think places reserved for every event in the forseeable future.
JulesG if you search on Picasa or Flikr for Le Mans Classic there are 1000s of photos to show you what the event is all about.
