Usually a good turnout of cars attending - mainly trads but sometimes the odd Aero. Its a good social occasion to meet other owners over a coffee and a bacon roll (order your roll on arrival!) You can have a good look around the workshops and showroom and of course buy anything from an accessory to a car.
I think people generally arrive from about 10.30 onwards. The parking tends to filled up - so best not to be planning on leaving early! The gathering breaks up around mid-day or shortly after - usually with cars being dispatched in small groups with instructions provided for a scenic drive through Kent countryside usually involving a finish at a suitable hostelry.
Its low key and relaxed - a good way to meet and talk to owners and swap experience/knowledge.
