You're just striking out all over the place.
Drivesrt.com has the requirement that your car had to to be built after Apr 1, 2005 to qualify but when I registared about a year and a half ago the requirement was that your car had to be ORDERED after Apr 1 2005. Silly me thought that since I bought my 6 off the lot then this order requirement did not apply. Guess what? I was right - that little bit about ordering referred to when the DEALER ordered the car. Turns out my dealer had technically ordered my car in Mar 04. Pretty neat trick since my car was built in Jul 04. So the dealer merely put in a request for x number of 6s and mine was shipped when it became available. One of my arguments in contesting the credit card charge was that the order requirement made no sense because my car could not have been ordered specifically since it had not been built yet. I also used the argument that the order requirement was misleading since no one would think that it referred to the dealer.
I attended the TE in Oct 06, got my credit card statement in Nov 06, contested the charge right away and the charge was dropped in Dec 06. Right about the same time the wording was changed from ordered to built. And I have a sneaky little suspicion that that was because of me.
The other major argument I used was that at the time Chrysler.com listed the track experience as a feature of the 6 with no restrictions noted. Now of course Chrysler.com doesn't list the 6 as a Crossfire model anymore so that little tidbit is no longer available.
