Specifically, average costs of repairs, insurance and gas add up to just $1,942 in Iowa, $1,973 in Ohio and $1,999 in Illinois. Other inexpensive states for car ownership include Idaho ($2,001) and Wisconsin ($2,108).

In addition to Wyoming, where the total cost of operating a car comes in at $2,705, other high-cost states include Louisiana ($2,555), where the average insurance premium ranks the highest in the nation at $1,277. Florida residents suffer with both high insurance rates ($1,124 on average) and higher-than-average gasoline expenses ($1,015), causing Floridians to pay an average of $2,516 to operate a car.

Mississippi ($2,487) and New Jersey ($2,421) are also among the five most costly states to own a car, thanks to high repair and insurance costs in New Jersey and high gasoline expenses in Mississippi.
