Ana's VW Bug could not just be sold with out her knowledge. It would require the title or release of interest, either would need to be signed by her. This is true if it's sold to a person, dealer or junk yard.
Why is the BDSM community critical of Fifty Shades?
In short: they feel Christian Grey is not representative of a BDSM practitioner, feeding negative stereotypes.BDSM practitioners are fighting prejudice and misconceptions from the general public, just like for instance gay / lesbian / transsexual people have been for a long time. The stigma from the public of living in an unconventional relationship is causing distress and harm. Practitioners are being called "sickos" and other such demeaning, unjust labels.The main reason for this stigma is lack of awareness among the general public what the practice is all about. And a big source of that lack of awareness is that popular culture very rarely portrays characters engaged in the practice, least of all healthy BDSM relationships.So when Fifty Shades breaks finally through this barrier and becomes popular culture, BDSM practitioners are distressed to see that the main character...* is portrayed as severely emotionally dysfunctional* engages in some questionable behavior that might be considered abuse* eventually gives up on the BDSM practice when he has been "cured" of his dysfunctionThey feel this feeds into the negative sterotypes about BDSM and as such they are critical of this series and its portrayal of people in the practice.It is interesting to note that this upset mirrors the upset that followed the movie Basic Instinct in 1992; when lesbian characters were finally shown in a popular culture hit, they were portrayed as murderers. This caused the lesbian community to criticize that movie.
