I just purchased a 2001 SLK-320. Love the car, what a blast to drive. Also looks great parked to my S-500 Coupe. So here's my question. Between the seats attached to the bulkhead are two plastic hooks, not the buttons for the windsock but two hooks. I've searched the owners manuel and find no reference to these. Anyone out there have any ideas? Thanks and see ya on the road. Ed Vozza
