^ That happens in a lot of markets. People capitalizing on demand. Especially when a product is in limited supply and is first released. Everything from Playstation, Justin Bieber tickets and GT3 .
Speaking of GT3, I read that a 991 GT3 RS buyer in Toronto with an allocation has already agreed to sell their car upon receiving it for $75k over MSRP. Not a bad pay day for just buying a car. Then dealer #2 will probably inflate the price and make money as well.

Are asking prices for GT3RS/GT4 etc crazy? - Page 2 - Rennlist Discussion Forums
That NSX seller may not be a flipper. They might have decided to throw it on Ebay and if someone pays a ridiculous price... well there are other cars to buy. If it doesn't sell they just keep and enjoy. Win win. Of course their ad drips with salesmanship.
