After heavy rain, water pours down at the junction of the driver's side left front window and left driver's side rear window no leak at all on other side of vehicle. Car does not leak at all when going through a car wash. Only occurs when heavy rain/soak vehicle. It appears that water accumulates in the track somehow because rain may have diminished, but there is still water falling down on my left shoulder. Is this the seal between front/rear roof panels? Roof side glass seal? Advice from members greatly appreciated. I have applied lubrication to all rubber seals using Mercedes specified grease. (New to site, so pardon if already covered in threads.) TY

Do you have a solid panel roof or a sunroof? Check where the solid panel or the sunroof meets the marrow panel over the door. Look, is there a space between the two? The center is known to delaminate from the side panels letting water leak in.

The above is good advice, also the rubber seals directly above the window glass can also leak exactly that way.
Difficult to know exactly which problem that is, might be worth contacting a specialist for convertible roofs, there are a few in the UK, guessing also some in the US?

Maybe run a strip of tape front to back over the area shown in my photo. This could be a temp seal and pour a lot of water over the area as if it was hard rain—way to test if this is the leaking area.

Thank you all for comments. I will do some simulations as suggested with tape and proceed
