Depreciation doesn't just affect the resale value of your new car. It also has an impact on the insurance money you'll receive if you total it.

Liberty Mutual feels your pain, and includes new-car replacement as part of its standard auto coverage. If you total your new car within a year of owning it and within its first 15,000 miles, they'll give you the full value minus any deductible.

The idea was so popular that they dreamed up Better Car Replacement for customers who don't drive this year's model. The optional coverage, which costs on average $60 per year, is now available in all states except Kentucky and North Carolina.

"Better Car Replacement works like this: If your car is totaled, we will give you the money for a car one model year newer with 15,000 fewer miles on it," says Liberty Mutual spokeswoman Nicole Guidara. "For example, if you total a 2008 Toyota Camry with 60,000 miles on it, we will give you the money for the value of a 2009 Camry with 45,000 miles on it."
