Those are pre production mules, test cars or show cars. Production was scheduled for 2-16 and then slipped to 3-16.
Roll out in 2008 was initially looking good then quickly bogged down with option issues from suppliers, litigation, and GM looking to cut corners to save money.
My 2SS is still on order - as there is no rush to cancel it due to GM not getting the pre-orders built until 10-09 or LATER. Initial ordering window opened on 10-13-08.
CAFE,GOVT regulations and GM's own design and RPO approval structure is like a Boa constrictor wrapped around the entire roll-out.
Oh yea there is that little detail about GM going broke too. Not holding my breath on getting a car that I want to buy any time soon.
