"USAA is the only choice."
I was fortunate to marry someone who is USAA-eligible. Our auto insurance premium for three vehicles is less than what I was paying Allstate for two vehicles before we married. When I called the Allstate rep to cancel, he asked me to give him a chance to keep our business, and inquired about the competition. When I said USAA, he paused, congratulated me, and said he wouldn't bother to work up a new rate quote because he knew he couldn't beat them.
Just going by Mike's nom de plume here on FR, he should be USAA-eligible (not sure if its just limited to officers anymore).
Their price is good, but their service is the best. Always. No exceptions. I'm a 19 year member.
