Regarding entry cost, this is what the organiser Malcolm Dudley told me when I said I was not showing a car but simply coming to see the others:
"The rally is adjacent to Hatton and you do not have to enter their site to attend the rally.
We are charging £6 for the rally pack which includes a program, rally plaque and a gift."
This seems to be the same as if you are showing a car, from what the website says, so in effect it is free to show, or to put it another way, when you've finished admiring the microcars, you can come along and admire my daily driver...
