In all honesty...the pricing is ridiculously good...providing the car lives up to expectations as they've been set over the course of the last year.
I'm sure there's a multitude of reasons for the configuration options as they exist, certainly most of which serve to control cost and allow GM to deliver at the exceptional price point. The fact that they are positioning GMPP to deliver at launch clearly indicates an understanding of the communities that will look to this car and offering to fulfill that 'need'. While it may not be on the order sheet...it looks like most of it will be in the parts bin.
I have really been impressed with GM's launch of the car to date...very impressed. Now...BMW sent me an invitation to drive the new M3 on the ring....I'm still waiting for that invitation from GM...
