Very rare (no Bose label) this 300 ZX door speaker grille is new-in-box with original bag and seal.  This one was never used with unmolested screw holes and securing tab.  No storage "rash."  It was purchased from the Bellevue, Washington Nissan dealership in the '90's' - stored in a heated closet since then.  

 My 1990 300 ZX Twin-Turbo had door speaker grilles without the 'Bose' badge.  Very hard to find, as most NOS or used grilles have the logo on them. This box and grille are perfect in every way.  These are hard to find in this condition - so don't wait!
