Hello, I would like to buy myself a Pontiac Firebird Trans Am, preferably with T-Top. The “old” models from Smokey and the Bandit (1970-1981) also alternatively 1982-1990 now, what do you have to pay attention to when buying such a vehicle? Where are the really critical ones?Weaknesses? doesn’t want to buy anyone with the anger pre-programmed. Does anyone know where to get such an exemplar from?
