Well after reading about rust on W210 estate doors I had a look under the top rubber seals, gulp, shock horror. Three doors gone well rusty.
Trying to get it sorted out next week with MB in Stuttgart as I live in Germany. I will let ou know how I get on.
It is a real sickener as I thought this car was superb until now. Only had one problem in six years.
If you own one then brace yourself but do have a look.
bye,
