With the Boxster in the garage for the winter I am working on a couple of things.
The passenger window continues to cause problems because it does not drop enough when the door is opened. I have tightened up the regulator cable and it seems to be better... I will report back with details after further testing.
The big project is reupholstering my seats which is described in this thread.
