Two different pricing models. State Farm prices a lean baseline and spreads costs across the largest auto book in the country; Liberty Mutual builds its pricing around customization, and the flexibility tends to show up in the base rate. In our 540 matched pairs the gap averaged $46/mo on comparable full coverage.
Sometimes. Penny's fine-print note: better car replacement, deductible fund, and original parts replacement each carry their own terms. Total the 3 you would really use, then compare bottom lines, not base rates.
