This was my first car & it was never reliable. It left me stranded so many times that it's a miracle that some psycho didn't attack me on the side of the road. (This was before cell phones were popular.)
The car stalled numerous times. I would often pop open the hood & hit some part with a screwdriver & that would fix it temporarily.
The car never had heat. (not fun living in a cold climate)
One garage refused to work on because he said the car was junk & not worth his time.
After the car spent 2 days at another garage, I had stopped at the gas station on my way home & it died again & had to be towed back.
I'm sure there are some well made American cars out there, but I haven't driven one yet.
Don't feel bad I had a 1986 Plymouth Horizon once, it didn't stall, but the heater sucked and it took forever to start in the cold weather.
Sounds like you never took care of it.
Heat sucks?..Replace the thermostat..3 dollar part.. a monkey could do it in no more than ten minutes.
