GpC reduced calendar next year

[Mike Bell]

GpC, now running at Peter Auto meetings in mainland Europe, plus the Silverstone Classic, have struggled to get decent grids this year.

It has been reported in Motorsport News that next year they will only have 4 outings, which includes Le Mans Classic, where in 2016 they attracted over 40 entries. So is there one particular reason for the low turnouts this year (incl Silverstone last w/end), or are there several factors involved?

It also feels like the UK STCT (SuperTourer) series grid sizes have dropped, although I haven't researched to confirm or deny, so apologies if it isn't the case! There was a healthy turnout at The Classic, at least. These cars, like GpC, are virtually all original championship survivors, so extremely valuable and almost impossible to replicate. Could that have a bearing on how often they are raced now?
