The Most (and Least) Expensive Vehicles to Insure

The Mercedes-Benz SL65 AMG is the most expensive 2011 model vehicle to insure in the United States, according to a new ranking of average premiums for 2011 models that Insure.com released earlier this month.

The rankings, which the insurance information and shopping site publishes annually, are based on the premium that a 40-year-old man with a good driving record (no speeding tickets or accident claims), a good credit record and a 12-mile commute would pay annually.

The insurance data company Quadrant Information Services calculated the average premiums for Insure.com by averaging late December 2010 car insurance rates from six large carriers across 10 ZIP codes in each state.

According to the results, the national average annual premium for the SL65 AMG is about $3,544 — 17 percent higher than the cost to insure the most expensive vehicle in last year’s results, the Porsche 911 Carrera GT2.
