Keeping a low profile
There was a time when the 'breaking cover' of new Formula One cars was done in the total absence of razzmatazz, without even a cover or used sheet present.
Invariably a technical honcho (no fancy titles in those days) from a team would point to a grubby, unpainted form in the back of a garage, and suggest to a journalist who happened to be present more by accident than design, 'it's our new car'.
Said scribe would hang around, and eventually the team's ace would arrive by road car (probably Mercedes-Benz, as the German company had a monopoly on such matters through a particularly attractive new-car discount scheme offered to all Grand Prix drivers despite the company not being active in the category for over thirty years), and proceed to turn a few exploratory laps in the latest Fastkar BXX.
