About $1,545 a year for full coverage on a national average — 7% more than the $1,438 average car. Insurers rate the Pontiac Grand Prix at an index of 107 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2006-2008).
The premium isn't spread evenly across the Pontiac Grand Prix: Medical payments — medical bills for you and passengers — carries its highest loss index at 135, while Property damage sits at 87. Those 48 points are the real reason behind the price, and they are the part a quote form never shows you. Against what the car is worth the bill looks different again: a 2008 Grand Prix sells for a median $5,450, so a year of cover costs 28.3% of the car's value. Over 3 generations of data the index has climbed from 98 (2004-2006) to 107 (2006-2008). Calculated from 3 insurance-loss records and live US listing prices.
Why a Grand Prix costs what it does
Insurers don't price a car with one number — they track losses separately for each kind of cover. An index of 100 is the average vehicle, so anything above means this model generates costlier claims of that type:
Read it as «where the money goes». A high Collision figure means these cars are expensive to repair after a crash; a high Comprehensive figure points at theft, weather and vandalism instead. Estimated annual split at $1,545: Liability (BI + PD) $742 · Collision $433 · Comprehensive $185 · Other (UM / PIP) $185.
