car insurance,
For 2nd car, not much difference. FOr new car, you can find contact on yellow page and shop around, get a quotation from different companies, then call your existing company to cancel policy, at that point, your existing company may give you very favorable price to keep you, maybe far below the quotation from other insurers, then you can make final decision. So you have to shop around for best price. Good luck! Make sure all quotations are based on same package.
