I recently got renewal email for my other car. I acknowledged it and checked quotes with other companies. Since it's imported car, insurance options are limited and after a few calls, I decided to go with the broker that sent me renewal. Just wanted to change mileage to a bit lower than last year. When lade on the phone plugged in new mileage, she found me new underwriter that offered policy at 50% of renewal cost. So, pricing is almost random and may depend on the time of the day or such a small thing like mileage. Maybe this particular insured decided to insure more imported vehicles or maybe they only go for cars up to certain mileage, who knows.
