For sale is new LeatherZ armrest bundle for Z4 - black leather, black base. Door armrests included. Never installed.
More info and pics on LeatherZ website here: http://leatherz.com/Merchant5/merchant. ... de=Bundles
I want 160$ for it + shipping. It is the same price as on LeatherZ website, but you don't have to pay customs fees if you are ordering from EU and shipping should be much cheaper than when ordering from USA.
Interested also in exchange for z3 parts - let me know what do you have.
