For a seasoned old hand's dose of reality, often off record, there's Frank Williams. For reasoned, considered explanation, there's Ron Dennis. And for a sound bite or a laugh, there's Flavio Briatore. At Renault's Monaco launch, he didn't disappoint.
Flav - tall, strong on hair retention, wicked lopsided grin, perma-tan - cuts an imposing figure. Only Flav would get away with launch garb of stonewashed black jeans topped by navy jacket with grey trim - the kind first worn in the seventies by purveyors of dubious sandwiches on the London-Newcastle high-speed train.
Doubtless many of you will have listened to Briatore's launch interview on autosport.com last week, but without seeing Flav's face you might have missed some of the wry humour.
It's worth noting that he faced the media just after Fernando Alonso told all and sundry that Briatore was still his manager. Not so clear according to Flav, who was asked to clarify the champion's management position.
