Nancy had a 68 Firebird made for her, with a pink appointed interior. Pink Mist was on the palette as a Spring 1968 color, but what made Nancy's car unique is that it had a pink interior. The car was supposedly in an accident, and they made her another one.
As a side note, I believe Frank Sinatra did a commercial for a 68 GTO, so the Sinatra's were in tight with Pontiac. John DeLorean was always friends with Johnny Carson, and in 1970, Johnny had a 1970 Judge. When DeLorean created his DMC 2-seater, Carson was one of the first to receive one, and in fact invested in DeLorean's company, and had John Z on the Tonight Show.
Playboy Playmates received a car if they were Playmate Of The Year. Those cars are fairly well known, and they never presented them with a pink Firebird, or even a Pontiac, over all those years.
The Mary Kay pink cars started a little later, I believe 1969.
This 67 Firebird was probably a special order paint car. Somewhere in the GM palette was Pink Mist (or whatever name they went by). It may have been a Cadillac color, or perhaps Pontiac added it as a Spring 1967 color.
