I don't think the cooling systems are quite as much of a problem as they are on E36's, but I know the E46 M3 water pumps have problems with bearing issues. Might want to check into whether that is a problem on the other E46's. I think they'll usually start making a noise before they fail, but still that's not really something you should wait until it breaks to fix.
