your wrong about that. For numbers matching cars that is true, If my car was a GT390/4 speed car you might get more if it were restored to stock. However my car being a fun of the mill fastback with a 289/C4 stock it wouldn’t be worth much at all. However being that “e” cars are so popular being arguably one of the most well known muscle cars of all time and demand they bring VERY high numbers. Its nothing out of the ordinary for these cars to bring six figures.
