From what I have picked up, Ma Mopar commissioned that job to coach builders ltd in florida to proto-type the set up. No paint work, all clean.
After it's show stopping, head turning, and award winning style was over at SEMA, Chrysler called it home for review. It is rumored that the reason for the call home was to be destroyed! The builder was not warned as other shows were scheduled...
Now it gets interesting...there is rumor that they are building a follow up car for the 09 SEMA show...I can't find pics and I have no proof, but the rumors have been floating around recently. Supposedly it will be retribution for the lost car.
I had a friend who works at a Dodge dealer run the vin on Droptop....it does not exist, but he noted that would not be uncommon to remove a specialty built show car from the database.
If you know anything, post it here.
