I personally will never use Allstate again. I had Shelby Lancer #071 insured through them. Had an SUV pull in front of me (also insured by Allstate) and totaled the Shelby. Fought them over 6 months and finally settled with them for more than SIX TIMES what they had initially offered me for it. Then I had to sue them/other driver to have my medical bills taken care of.
Ask DodgeZ and DodgeZDad about the Allstate issues, if they remember! It was a pain in the butt, but DodgeZ helped me out immensely (among others) in getting me a fair settlement.
IIRC, a few members switched carriers from Allstate because of the way they handled my issue/talked to the owners of collectors Shelby's, etc.
