Stefan,
Yes, I think you are probably right for the vast majority of people. On my side here is South Florida is the demographics where there are a high percentage of well-off people in that age bracket. Still, I am reluctantly becoming more convinced that the niche market for classic Genesis grills is pretty small. My own personal life with too many jobs, complicated family dynamics, and lack of space to work efficiently has never allowed me the privilege of putting the kind of time I would like into redoing a bunch of grills and really finding out what how my market will respond. Between that reality and some of the conversations here, I am coming to realize I probably will need to content myself with being a collector and an occasional restorer of a grill here and there. Steady production isn't in the card for me right now, and I am not sure anymore that there is a demand for what I would be creating.
It is a little like the collector car hobby (which I can't afford to participate in). The magazines are full of articles about the future of all these restored older cars that the younger generation mostly is uninterested in.
