Ok actually it goes like this the '76 50th Anniverary TA was the original triple black car. Not many people even knew about it as SATB had not come out yet. In the film it was basicly the '76 with the updated body improvemnets for the '77(basicly hood and shaker scoop and different bezels on the headlights) and retained it’s 50th aniv. black vinyl interior. This was also the first year of the “6.6 Litre” designation for the 400 engine as the 455 was put out of production. In the '77-'78 model year the car was released as a production car for “Bandit buyers”. Same car with more gold trim inside and out such as the gold spoked steering wheel and instrument facia was sold as the Pontiac Trans Am SE(Y82 special Edition).
