Six tips to find cheaper car insurance
It doesn’t matter where you live, car insurance is going to cost more than you would like. Even the states with the best rates would not really be considered “affordable”. But there are some ways you can make sure you’re not overpaying for car insurance no matter where you live.
- Buy vehicles that are cheaper to insure. The vehicle you drive has a huge impact on the cost of car insurance in Portsmouth. For example, a Volkswagen Atlas costs $588 less per year to insure in Portsmouth than a Subaru BRZ. Insure cheaper models and save money.
- Obey the law to get lower insurance cost. If you want cheap auto insurance in Portsmouth, it’s necessary to be an excellent driver. As a matter of fact, just a couple blemishes on your motor vehicle report could end up increasing insurance rates by up to $512 per year. Major misdemeanors like driving under the influence could raise rates by an additional $1,772 or more.
- Avoid filing small claims. Auto insurance companies give a discount if you do not file any claims. Auto insurance should be used to protect you from significant financial loss, not for small claims.
- Remove unneeded coverage on older vehicles. Deleting comprehensive and collision coverage from vehicles whose value does not support the cost of the coverage can cheapen the cost substantially.
- Shop around anytime. Taking a few minutes to get some free car insurance quotes is a smart way to save money. Rates change often and you can switch anytime.
- Save money due to your occupation. Most auto insurance companies offer discounts for specific professions like architects, nurses, members of the military, police officers and law enforcement, doctors, college professors, and others. If you can qualify for this discount, you could save between $57 and $185 on your yearly insurance cost, depending on the age of the driver.
