I don't see however how that can be recreated, they had for many years managed to bottle lightening. That's a once in a lifetime situation for a brand. Without access to the numbers it's hard to make a fair assessment of whether or not they successfully leveraged that opportunity, the collector consensus seems to be that they did not but I think that is always colored by what happened to that specific subset of owners which was/is a very small share of the customer base. It could be a very interesting business school study I think!
