All speculation and rumours for now so not to worry.
The rumour of the polymer panels being fazed out only pertains to the
upcoming Relay Van. There is talk of going from 5 to 6 speed in the ION.
Polymer is here to stay - for now. But then Saturn engineers are like the
weather in Florida, just wait a few minutes and it'll change again. I also
agree that if they do away with the polymer panels it will greatly influence
Saturn loyalty.
