I just noticed quite a bit of rust around each license plate light on my '88 325iC. This is the only rust on the car that I can find. Since the lights hang down and the trunk overlaps them, I don't know what the source of the moisture is. Is this a common problem? Are there any drain holes or gaskets I should check? My trunk stays dry. Thanks Sid '88 325iC BMWCCA 162176 ------------------------------
