Saturn made small well built cars and GM is closing the plant WTF?

Saturn was a spin off of GM started around 1990. They specifically built a brand new state of the art plant, away from Detroit in Tennessee. From day one they were to be a different kind of car company. They made very well built cars, cars with Hi-Tech Polymer bodies that were light-weight, didn’t dent, didn’t rust. They looked good and got good gas mileage. It was GM’s way to build a Japanese car in America by an American company. They also sold them differently. There was a no haggle price tag on the car. You paid the price on the car without the sales weenie tricks. The showrooms were bright, futuristic, and you could eat off the floor of the service bays. I know all this because I was so impressed by them when my fiance now Wife’s car was stolen I told her to take a look at Saturn. She was all set to buy another Japanese car because she loved her Mazda that was stolen. She went, without me and bought a beautiful 1992 Saturn SC 2 door sports coupe. It was sharp, responsive, solid, and got great gas mileage. It would go well over a hundred yet get as much as 37 miles to the gallon with it’s 4 cylinder DOHC Fuel Injected engine and 5 speed. We sure got our monies worth out of that car. She paid about $13,000 brand new. $3000 less than the comparable Toyota or Mazda she looked at. We owned it for 13 years racking up over 135,000 miles. It never had a major breakdown. Cost of ownership was low. We sold it because we outgrew it, it was small. Because of the plastic body it looked as good on the outside when we sold it as the day she bought it. We got $750 for it and the couple who bought it was thrilled. My Brother in law bought his Saturn 4 door sedan from his sister for $700.00 He has now run it up to over 175,000 miles. Regularly gets over 35mpg on the highway and loves it. and he is a Car Fanatic. The point to all this is Saturn was and is building the kind of cars that the Government says GM needs to build to survive. They have a full line now from their small cars, to bigger sedans, small SUV’s, and even Sports Car . Plus they sell a flex fuel and a hybrid. So I was shocked to see GM is closing them on November 9th. What sense does that make? And if they weren’t selling then what kind of little green econobox will GM make in Detroit that will sell? I just don’t get it. If you do, please write and explain it to me, I’d love to understand. Thanks, Spiney
