For sale is an excellent condition OEM Porsche rear trunk liner for a 2005-2006 (mid July) Boxster. It is just like the one in this Suncoast link:
Rear Trunk Liner:Porsche Parts & Porsche Accessories - Wholesale Porsche Parts & Tequipment
I am also selling a front luggage compartment liner, and these can ship together to the same buyer to save on shipping costs.
$48 plus shipping (1/2 the cost of the Suncoast price).
