This is an argument I have regularly. You can have rare cars due to few made. However you can have statistically rare cars where many were made but few are left, as well. From the point of view of looking at cars for old times sake, therefore, it might be argued that a 1100 MK1 Estate/Countryman is more interesting than a Scootacar. This ignores eccentricity of build, of course. That is, perhaps, subjective. But I understand the rule they wish to apply. I do not doubt that a Powerdrive and a Nobel, driving, stole the show for many of those attending.
