Seems to be organised along the lines of the HPOM event at Broadlands, but only a one day event, also there is camping available on the Sat.
As can be seen from the booking form http://www.classicmotorevents.co.uk/pdf ... l_2012.pdf
the entry fee of £3 per car seems reasonable, also I believe that if a Club can field at leat 10 cars then they will allocate space for a Club Stand with no extra fee

Wish I had spotted this earlier as it would have been an alternative venue for SDD, (not as exotic as Beaulieu but a more reasonable cost).
