I am no expert on BM cars, but there were different phases you could order from mild to wild. The revell '69 BM Camaro represents the wild phase III car. I have seen pictures of cars being represented as BM cars that looked relatively mild except for a few aftermarket parts thrown in, perhaps these are the phase I & II packages. As I understand it, these cars were built to order for the customer so no two were alike. Unlike the Yenko cars which were all built to the same spec.
