Coverage at a glance
What each carrier offers in standard policies.
Liberty Mutual
Liberty Mutual's coverage breadth is its strongest argument. The 'better car replacement' rider replaces a totaled car with one model year newer; accident forgiveness is available; new car replacement covers depreciation on cars less than one year old. Available customizations exceed what some lower-cost competitors offer.
Add-on coverage
- Accident forgiveness — First at-fault accident doesn't raise rates (terms vary by state)
- New car replacement — Replaces totaled vehicle with current model year if within 1 year of purchase
- Better car replacement — Replaces totaled vehicle with model year newer than yours
- Original parts replacement — OEM parts used in repairs instead of aftermarket
- Lifetime repair guarantee — Repairs at Liberty's authorized network shops carry a lifetime warranty
Mercury
The bottom line
Liberty Mutual
Liberty Mutual works for drivers who can stack 3+ discounts (homeowner + multi-car + telematics) and who value specific endorsements like better car replacement. For typical single-policy drivers, Liberty is rarely the cheapest option, and the customer experience scores don't make up the price gap. Always price Liberty alongside GEICO, Progressive, and Travelers — and lean heavily on the bundling discount if you have home or renters.

Mercury earns a quote if you're in California or one of its other operating states and price is your dominant criterion. If you're outside its footprint or you'd trade a few dollars per month for better claims experience, look elsewhere.
