Noisy cabin in 2003 Convertible M3

[Bimmer2004]

I bought a used 2003 M3 Convertible recently and the cabin seems a little noisy compared to my old BMW 323 Convert. I hear a creaking noise from the rear drivers side. I may get used to it but it seems louder than normal. Only when tops up. Anyone experience or does something may need to be tightened?

I would just tell the dealer, however, My guess is it is the window, on ours, if a window has broken before, so be gentel when slamming the doors...Another comon problem is the seals on the top squeaking, nothing some silicon cant fix...tell the dealer
