I received an email on 28 Feb. 2012 from CCA titled "Don't Slip and Power UP!". It was a request to input for the topics "Would you buy an OEM limited slip differential?" and "How about an M-Powered hatchback?". But 6 days later, I tried the link and the survey said it was "closed". I'd like to at least see what was asked and what everyone's response was. My answer would have been ABSOLUTELY YES!! to both questions. Jay 155365
Ditto, but I only got the e-mail on Friday (4 days ago), and couldn't respond. FYI - the bmwcca@bmwcca.org email address is full, so I was unable to voice my disappointment about not being able to provide my feedback.
