I agree with others that the number of Porsches available on eBay could be a seasonal thing. I would also add that eBay is a growing marketplace and the increased number of Porsches available could also be the result of this growth. eBay has critical mass, and there may be no better place to put your Porsche where it will be seen by so many eye balls!
Regarding politics on a Porsche board:
Perhaps next we can debate religion and its influence on Porsche ownership?
Best to you all,
