Sensitive much??
This is actually a really important (and interesting) part of this story. Interesting because, as others have stated, I've never heard of being able to finance a car without full coverage. This has NOTHING to do with your financial situation - it's merely interesting since many of us didn't know this was even possible. I've had 3 different car insurance companies (State Farm, Geico, and Progressive), and all required full insurance since I don't "own" my car.
It is also an important part of the story because you are still paying for a car that you can't drive because it caught on fire. If I were you, this would give me more impetus to fight with GM because not only did my car catch on fire, but I wasn't given money to get another one (as you would have with full insurance).
