I've been buying and selling on ebay since 2001, while I am not interested in the cars I do notice them and the level seems to be about what I remember seeing over the years. I would say that the parts offers are up this year, topping 500 items. Over the years I see the same stuff, hats, ads, etc, etc. but the good stuff is lurking in there also. Since I'm coming to the tail end on mine I don't need much, so I don't spend much time on ebay. The fact still remains that ebay gives you an enormous market to sell your items at.
As Randall pointed out 30 cars on ebay would hardly be considered dead.
No Kentville, I think our hobby is alive and well on ebay!
