Like the title says "Blind Spot.................. IDIOTS !!!!!!!", I am trying to order a 08 fully loaded GT, yet the sales people and sales manager either DO NOT know what I am talking about or they say it is a dealer installed option for an extra $600.00 !!!!!!! As far as I know it is a factory installed option. I just HATE the fact that people have NO CLUE about a product that they are selling. So can tell me if they know, factory OR dealer installed option ??? I think factory.
