Sadly, sold my baby (1971 280 SL) so selling like-new hoist to lift and store your 113 hardtop. Unlike racks, top can be removed and installed by one person.
All you need is 3 feet or more clearance above the car top when installed. Includes heavy-duty winch, cable, pulleys and custom straps. New costs $200. All yours for $75 plus shipping.
I've added two pics: first is the winch mounted to the wall, the second shows the ceiling pulley with the straps attached.
Both pics need to be rotated 90 degrees clockwise (don't ask me why they came out this way!).
Thanks for the interest all!
