Not an original but a fibreglass replica purchased during a Group Buy on www.S14.net
with about 30 other people.
It's been painted diamondshwartz (black) and the flap is flat black. I've only installed it once and then removed it and put the stock one back on. It needs some work on the flanks as we filled it with high density foam and the flanks bulged a bit. It's an easy fibreglassing repair though.
I have pictures. Email me and I'll send them to anyone interested.
As for price, I have to look back in my books. Turner sells the original BMW piece for $1600 USD plus shipping. I think I paid somewhere around $500 USD plus shipping for this replica......... and then had to paint it. But I'll check and post up a price once I can find it.
