The bases of both doors on my 2000 car have rubbed through the paint to the metal on the main body tub. I'll address this over the winter and prevent it happening again by fitting appropriate rubber sealing material. I've checked and am satisfied that the hinges and door mounts are all in perfect order, and that the door latches are correctly adjusted. I'm just wondering if anybody else has experienced this and if it's normal.
I note that later cars appear to have been fitted with rubber door seals, probably to prevent this??
