We of course have full coverage. Definitely not dirt cheap though. I pay ~$185/mo for the two of us. It keeps getting more expensive and I don't know why (no at fault accidents or tickets).
The rental is covered, the tow is covered, it's covered if the other driver has no or insufficient coverage, medical payments and personal injuries are covered, so that's all good.
I have gotten quotes from other insurance companies but their level of coverage for the money does not come close to USAA.
