I'm new to the BMW soft top world, so I have some simple questions:
1) Does the rear window blanket come with the car or is it an add-on option (I didn't get one with the car) ?
2) Is the rear window blanket necessary, does it really help maintain the window and/or does it do anything else?
3) Should I be putting anything on the soft top (perservative, waterproofing, etc.)?
4) Any additional maintenance items that a hard top person (like me) wouldn't know about?
