I noticed after a heavy rain shower last night the carpet in my 2004 SL55 AMG behind the drivers (RHD) seat was wet and water droplets were coming in from the rear quarter panel roof area where the hinge is. All the seals were replaced a couple of years ago so the previous owner told me and there are no water leaks anywhere else the boot is bone dry. Has anybody any ideas as to point me in the right direction to curing this. Thanks
