Frist there IS a cost for
Frist there IS a cost for everything in a vehicle. Adding exoctic materials while saving weight also dramatically adds to the cost.
Right now, the ATS built the way I would order one is just under $50K (TRUE!). That's a push for me but Im almost certain I'll buy one after an extensive test drive.
As to yur comment about Collin Chapman, a man to be respected for inovation, he killed some reace car drivers through going overboard on weight reduction. He made some of his cars so unsafe that some drivers refused to work for him.
I'll take the ATS as is thank you.
