Just an observation really but I note that most of the cars in the photos from the above two events show a distinct difference in car style between the cars in Cup & the cars in Classic - the photos of the Cup cars show that most of them are the more modern "smoother" body style (or the fully enclosed) whilst the cars in the Classic race/ class are clearly more of the traditional & less smooth bodywork style.
Is this just an accident of entries or is there a move to have the Cup cars look more modern &, dare I say, sleeker? Both "styles" have their place but perhaps a sleeker style in Cup would help promote he image of the series as being modern.
