I must admit that there are big holes in the way the list was compiled... For instance, a 'muscle' car suggests a gran touring V8 from the late 60s to early 70s, before emission regulations were introduced. Yet there were many later cars included on the list. It did include cars from all around the globe, but there was no mention of the Buick GSX, or the latest MB 63s... I haven't got a copy handy, but I don't think it had the GTO, or GT40 either.
Clearly a flawed list, but good that a classic did get a mention.
