Some additional insights into insurance rates and possible policy discounts include:

• As you age, car insurance rates tend to get cheaper. The difference in 2024 BMW Z4 insurance rates between a 50-year-old driver ($2,290 per year) and a 30-year-old driver ($2,764 per year) is $474, or a savings of 18.8%.
• Gender and age are two big factors. For a 2024 BMW Z4, a 20-year-old man will pay an average rate of $5,192 per year, while a 20-year-old woman pays an estimated $3,728, a difference of $1,464 per year. Women get significantly cheaper rates. But by age 50, male rates are $2,290 and the rate for females is $2,232, a difference of only $58.
• Improve your credit rating to save on insurance. In states that have laws that do not prevent credit score data to be used for the purpose of coming up with an insurance rate, having a high credit rating of over 800 could find savings as much as $407 per year compared to a good credit rating of 670-739. Conversely, a subpar credit score could cost as much as $471 more per year.
• Violations and tickets cost more than a fine. If you want the most affordable price on Z4 insurance rates, it’s necessary to not be an aggressive driver. In fact, just a couple minor incidents on your driving report could increase insurance cost by as much as $680 per year.
• Higher physical damage deductibles lower policy cost. Raising your policy deductibles from $500 to $1,000 could save around $424 per year for a 40-year-old driver and $824 per year for a 20-year-old driver.
• Low physical damage deductibles may be wasting money. Dropping your deductibles from $500 to $250 could cost an additional $438 per year for a 40-year-old driver and $870 per year for a 20-year-old driver.
• Lots of policy discounts equals cheaper Z4 insurance. Discounts may be available if the insured drivers are accident-free, take a defensive driving course, are military or federal employees, sign their policy early, or many other policy discounts which could save the average driver as much as $442 per year on BMW Z4 insurance.
• Get cheaper rates because of your employment. Some auto insurance providers offer policy discounts for working in professions like the military, doctors, emergency medical technicians, engineers, lawyers, and other occupations. Getting this discount applied to your policy could save between $78 and $228 on your annual Z4 insurance cost, depending on the policy coverages selected.
