just bought an '01 Boxster S and found this under the seat. had to google the part number to ID it. assuming this car had a hardtop at one time, doesn't now. they dell new for about $20, so it is not really worth the effort to put it on Ebay. if anyone needs this in the Nashville, TN area, PM me. I will meet you somewhere. otherwise someone can have it for the cost of shipping.
I also have the original radio/CD player and cd storage bin up on ebay.
