My dealership guy just got back to me about the "SS performance package" The one with the Recario seats and the LSD. It turns out it is aviable it just showed up in his computer today!!!! The package cost me $1400 - and I think it will be well worth it. The day that GM allows the orders to be set is MARCH 7, 2005. When I pre-ordered mine the 17 of Jan. the deal wasnt aviable but I went and changed it today at the dealership, it didnt seem to be a problem - FYI for those you have pre-ordered. Ok my job is done hope the info is helpful to those you were asking about the package.
