My CD manual - like a fool I sold the hard copy when I gave the 300SD to my mum, so I'm stuck with the CD.

While the CD has its advantages, I do like to while away the hours in front of the fireplace with the dog, reading the manuals. Can't do that with the CD unless I want to risk spilling Glenlivet on the keyboard.

The manual illustrates the vacuum lock on the driver's door. Heck, even Rusty fell for that one.
