Liability auto insurance protects you from that worst case scenario by providing a cushion between your assets and the amount you’re on the hook for. For this reason, choosing the right auto liability limits is the most important part of your car insurance quote comparison. NerdWallet typically recommends having at least as much liability coverage as your net worth.


Unfortunately, the cost of claims has been rising in recent years for cars on both sides of the list, mainly due to technology. “All of the sensors and other technology in today's cars have pushed up the cost of insurance claims,” says Walker. What was once a minor repair has become much more complex and costly. Complicated repairs also add to the time a car spends in the repair shop and usually requires the use of a rental car.”

The sticker price, high repair costs and what is under the hood can result in a sky-high premium. The 2019 BMW M760i xDrive, No. 5 on our most expensive list, is a good example. “It's little wonder that the M760i xDrive costs a bundle to insure, it's a small fortune to buy in the first place. The ultra-luxury sedan's six-figure price offers amenities like hot-stone massaging seats, retractable footrests and fragrance-enhanced ventilation — plus a 601-hp, twin-turbocharged V-12 that took just 3.5 seconds to scorch 60 mph,” says Mays.
State legislators set limits on how much a company can increase your rates after a crash. Our hypothetical accident resulted in only $2,000 worth of damage. That caused average annual rates to spike by $1,000 or more in some states, while others jumped by far less. One thing’s for sure: Your rates will definitely increase after an at-fault accident, so be sure to compare car insurance rates if you have one on record.
In addition, luxury cars come with high repair costs due to the quality of the materials used (teak wood is more expensive than plastic) and the fact that they are often loaded with the latest technology. “Sports cars and high-end luxury vehicles are almost always more expensive to insure because of repair costs. The materials used in these vehicles is often more expensive than the finishes in a moderately priced vehicle,” says Carole Walker, executive director with the Rocky Mountain Insurance Information Association
A history of chronic disease or other potential health issues with an individual or family, such as heart disease or cancer, may result in paying higher premiums. Obesity, alcohol consumption, or smoking can affect rates as well. An applicant typically goes through a medical exam to determine whether he has high blood pressure or other signs of potential health issues that may result in premature death for the applicant and increased risk for the insurance company. People in good health typically pay lower life insurance premiums.
