Highland Park seems to be less certain than the other service centers. I called them a bunch and they didn't answer on Saturday (to phone calls and email). After they failed to respond, I called Tyson's Corner and they confirmed my car was eligible (yay). The service center shouldn't go off the prior bulletin but rather the latest one from Friday (apparently in the WARP system).
After I called Highland Park again today, they finally answered and told me, initially, that I was ineligible (despite what Tyson's Corner said). After persisting, they acknowledged the WARP system said I could be uncorked but they still believed my car was too old for the uncorking and they would need to confirm it. Nevertheless I have an appointment Nov 2 and I will insist that they uncork it because it is eligible in their system (that information was known to them and they refused to uncork me a month ago). Hopefully it is smooth sailing.
