Casually having a stroll through Zebra Onehunga as you do and spotted a standard e39 fitted with black leather Sport seats.
Boot and all 4 doors were deadlocked so out with the holesaw again.
Leather is fairly good and all the electrics work but god damn were they in a state of filth. The drivers seat smelled of dog, sweat and mildew and the passenger seat was just mainly mildew and old beer smell.
Spent a good day of solid dismantling and cleaning of the seats. Used some baking soda and white vinegar to kill off the mould and other gross. Will be letting these air out in the sun for a couple of days before installing.
