Thankfully no evidence of any leaks on my w124 estate - I have heard about the rear window leaking problems though - I waxoyled around the inside base of mine and all inside the rear wings when the car was about 4 years old and repeated it every 2 or 3 years since. As a consequence the rear windows and rear wings are rust free - maybe it is rust that causes the gaps and leaks?
Also curious how the water found its way from the load area down to the rear footwell?
