I've still got a Firebird. Thing keeps getting better gas mileage every year `cuz stuff keeps falling off of it! Nice engine, but the rest of it is garbage.
They had to stop making them because of quality problems that "could not be alleviated." So all the losers that made (crappy) Firebirds were spread throughout Pontiac. Guess what? That made Pontiac a crappy division. Then GM rounds up all the guys who were skilled enough and worked hard enough to be employable and paid them to leave (via buyout and early retirement packages)! Losers that were unemployable wouldn't jump ship, so they stayed.
Now that the feds are major players in GM, everybody knows that the usual politics are just around the corner. Plenty of affirmative action, "fairness" in compensation, hybrids and all the environmental green as far as the eye can see are in the queue for Great Mistakes. If you are a deadbeat lazy loser who doesn't care to work for a living, GM is ready to be your sugar daddy. Especially if you are a member of a protected class (blacks, women, gays, etc.)
GM was the largest corporation in the world at one time. But it's been dying right along with Detroit. It was apparent after they bought EDS.
