The dealership in Maywood NJ never gave a shit when I gave them 1s. It took them months to figure out why my headlight's autoleveling wasnt working. Even when they finally replaced the whole housing they used a Euro spec headlight housing so now I have two mismatched headlight housings. So I gave them 1s again.
This system is screwed up, it doesn't help to give 1s, unless the dealer doesn't care. I don't feel like driving further to find another dealership when the one by me refuses to even do an adequate job. I wish BMWNA would punish the dealers for being this dumb.
