There are several reasons why it won't be run again in September and both are to do with money. Firstly Goodwood is the first weekend in September and the majority of spectators can't do both so they have to choose, but the main reason is because of the shops on the Hunaudieres straight who created merry hell because of lost trade. Having gone through the lean months of July and August they then were closed yet again at the beginning of September. On the down side (for the drivers) is the lack of available marshals in July. It takes 1,400 to run the 24 hour race in June but if my figures are correct they had only 450 for the Classic last year. However. some enjoyed it so much they are thinking of changing to the Classic since there is a waiting list to be a marshal for the 24 hour in June (like the Goodwood Revival) and many enjoyed the laid back relaxed atmosphere. It is after all their own free time they are giving. Last year there were 220,000 at Le Mans (55% from the UK) but the Classic was over 80% british cars and around 70% british spectators, so they can't afford to lose people. Petersport reckon they break even at 50,000. The first two editions in 2002 & 2004 lost money.
