I can recommend Duxford imperial war museum as a possible venue. The MGOC used to have their anual bash there and it is a terrific site ! Plenty of aircraft and stuff to look at, and it's just off the M11 and very easy to get to from most places.
OK it's not far from me, but of all the car shows that I have been to which is a lot, it is my favourite venue regardless of proximity.
