Same thing. I was with Allstate for 20 years. Have the house and everything else with them. Always had the cheapest car insurance and I would shop it every few years.
Ask for a quote on the MS - goes from $776 (2004 MDX and 2006 TL) every 6 months to $2150 every 6 (MS and MDX). Uh, no.
I checked with USAA as we bank there (You do NOT have to be military, but military gets better rates.) Went from $776 at Allstate to $850 for the MS and MDX at USAA.
