The above link if all true is a perfect example that nicely sums up how GM has allowed their loyal customer base to erode...and foolishly continues to do so!.
I can't help but keep thinking of how this whole GM thing parallels the old children's rhyme Humpty-Dumpty...the last line especially so!.
Try Substituting General Motors for Humpty and saying it a couple o' times yourself..
