Update: the AROC concours event will form part of the AI show at Stanford Hall on June 1st. The idea is to share the costs of hiring the grounds etc. among several car clubs, I believe Ferrari and Maserati clubs will also be present, plus any Italian car is eligible to join in the AI concours event.
AROC live will be held at RAF Woodbridge, Suffolk on August 31st. AROC members can take their cars onto the airfield circuit, with instruction if required, plus there are some competitive sprints etc. planned. Even a bicycle race for some reason - perhaps the toilets are a long way away
