Whether car insurance is more expensive for new cars vs used cars depends on the overall value of the vehicle. For example, a 20-year-old Porsche may cost more to insure than a brand-new compact car, like a Hyundai Sonata. That being said, when insuring a new and used car of similar make and model, it will generally cost more to insure the new car. Once you’ve narrowed down the cars you’re considering, you can call your current insurance agent to ask how the cost of your insurance will change after purchasing.
