I think all BMW model is designed that way for comfort and thus, less durable. E36 and E46 also need to replace this bush pretty often.. unlike Japanese cars, they can tahan easily 10 years.
What make matter worst is u need a special tool to open the bush..
This E46 M3 bush:
and this is the special tool to force the bush out. If not, you have use hammer to ketuk so hard, which can possibly damage surrounding parts..
