The story wieghs heavily on the Oldsmobile and Plymouth brands. I don"t think the SRT8 Challengers is in anywhere near the same class of car. This is certainly not your fathers oldsmobile...
Also not mentioned is how the discontinuation of a brand by the new parent company will be treated as far as warranty. Maybe Dodge brand gets discontinued so GM doesn"t have to back a "lifetime" warranty... or maybe there is a period of time that can be defined as lifetime in such a case.
May not be any simple black and white answers at this point.
