How to find cheaper Detroit car insurance

Smart drivers in Detroit are always searching for ways to reduce the monthly expense for insurance, so scan the tips and ideas in the list below and it’s very likely you can save a few dollars on your next renewal or new policy.

  • Buy vehicles with more affordable insurance. Vehicle type is a primary factor in the cost of car insurance in Detroit. As an example, a Hyundai Kona costs $1,234 less per year to insure in Detroit than a Subaru BRZ. Lower performance vehicles cost less to insure.
  • Clean up your credit for better rates. Maintaining a high credit score could save up to $654 per year over a lower credit rating of 670-739. Conversely, a poor credit rating could cost as much as $759 more per year. Not all states use credit score as a rating factor, so check with your agent or company.
  • Make your policy cheaper by raising deductibles. Raising your policy deductibles from $500 to $1,000 could save around $300 per year for a 40-year-old driver and $588 per year for a 20-year-old driver.
  • Compare car insurance rates before buying a car. Different models, and even different trim levels of the same model, have very different car insurance rates, and auto insurance companies can charge a wide range of costs. Get multiple insurance quotes before you purchase in order to prevent insurance sticker shock when you receive your bill.
  • Reduce coverage on older vehicles. Removing comprehensive and/or collision coverage from older vehicles that are not worth a lot can reduce the cost of auto insurance substantially.
  • Qualify for policy discounts to lower insurance cost. Savings may be available if the insured drivers are loyal customers, belong to certain professional organizations, sign their policy early, are senior citizens, insure multiple vehicles on the same policy, or many other policy discounts which could save the average Detroit driver as much as $702 per year on their insurance cost.
