After reading some of these threads I am so sorry I didn't pay more attention recently. A friend and I were at the most recent Pomona Swap Meet/Car Show in Pomona, CA. We ran across a 68 F/B 400, HT that was pink. The owner 'claimed' that it was a Miss America car so of course the first thing I did was look at the cowl tag. WOW! It was a special order paint code - Now I realize that doesn't mean that it was an actual pink car delivered to Miss America or Playboy, but I really wish I had taken down the vin for further research!
I looked the car up and down and unless someone painted it and did an excellent job w/ the jamming, etc. several years ago, this might well have been an original pink car!
Anyway - Just my contribution, there is likely a pink firebird out there in CA somewhere...
