Does anybody know whether it is possible to remove the plastic trim parts from the rear seats without breaking anything? I'm referring to the trim on the sides and top.
yes you can , i found removing the seat cover first helps , the side cover around the locking slot has 2 plastic pins , i drilled through the center with a 1mm drill and used a screw to pull them out , the top pull handle has tabs that lock it into place and can only be removed with the seat cover off to get at the tabs
