Why insurance costs what it does

IBC hasn't published claims for the 2008 yet, so this uses what insurers paid out on the 2008 model, compared with a typical car. Bars to the right mean higher claims, which push the price up.

How the grade is worked out

We estimate what a typical driver with full coverage would pay for this model in Ontario, then rank it against every other 2008 model. The car-specific part of the premium follows what insurers have paid out on this model (the bars above). A is cheaper to insure than at least 80% of them. It compares cars, not drivers: your own quote depends mostly on your age, record and address.

Safety

NHTSA hasn't published crash-test stars for this model year.

About these ratings

Stars measure how well the cabin protects people in a lab crash, not how often the car crashes. They're for the U.S. version of the same model year, usually the same car as in Canada. IIHS awards can depend on headlights or trim. How this works
