With Allstate, for full coverage on all three of my cars - the Benz, the Montero, and the Z06 - I paid $340 per month. Yes, that much.
Now, with the same coverage on the same vehicles through Farmers, plus renters' insurance, I pay $190 per month. That seems a bit more reasonable to me.
I had State Farm for my renters' insurance, and they were wonderful. Economically, though, it just made more sense to go with Farmers at this time.
