After watching how the local GM dealer in La Mesa, California treated my parents on a recall of a ‘72 Caprice for a piece of plastic in the carb (it took the THREE trips to replace a piece about the size of a hearing aid and 10 hours each trip), I sore I would never own a GM vehicle. And I have not despite being offered good deals on some classics.
What ever GM is suffering from is systemic and goes back decades, probably to Durant. Hopefully when the fold up shop in the near future because it will be easier to go out of business than settle law suits, their management will never find employment again.
GMs problems are systemic and go back at least 4-5 decades. Had they been forced to prove their right to exist they might have changed, but they were given a complete pass, so to expect that anything significant has changed at GM since before the bailout is foolish.
Push em through a real BK, make them take loans not bailouts to exist, force them to risk starving on the vine and they will change, until that happens its nothing but window dressing.
