the 'RaceStoppers' - a marketing campaign of Pure Oil that debuted at the 1969 Daytona 500, after Linda Vaughn went to work for Hurst, and they didn't want a replacement to outshine Pure Oil again

The cars are the 3 BME Baby Grand Cougars at Cotton Owens garage

Pure Oil (later known as Unocal), the gas company bosses decided it would be better if their beauty queen wasn't quite so famous, as Linda Vaughn's celebrity eclipsed the Pure Oil product.

 So instead of one girl whose popularity eclipsed the company's, they hired a bevy, ushering in the era of the Race Stoppers, four models in miniskirts and white leather boots who debuted at the 1969 Daytona 500.

Unocal's PR man at the time, Bill Brodrick, explained the Race Stoppers' corporate value to an oil company: "Nobody writes about gasoline or oil unless a car burns up," Brodrick says, "so how do you get some [good] publicity? . . . What better way than put four pretty girls with a race driver?"
