It's sad to hear about peoples misfortunes like this, but I'm quite sure that this car was not properly maintained. When the spark plug pops like this it's because of incompetence of the previous owner either over tightening or aligning it wrong. The threads does not just loosens like that.
Regarding the failing tops, and the other problems you've had it sounds like your car dealer is not up to standard. This comes from a man that's run a Neon for more than 142,000 miles with practically no problems. I've done all my own maintenance and these cars are extremely well built, I really can't point out a single design flaw in it's construction. It's still very rattle free and tight, even if it's more than a decade old.
You stripped the spark plug huh. Sounds to me like someone don't know how to line things up.

Mine is now about 15 years old. It has 83,000 miles. It squeaks, rattles and shakes. I've replaced nearly every part it has. Heck, even my frame has begun to sag slightly under its own weight. Dodge FAILED at beating the imports with this one. And BADLY.
