Cadillac's five-year zero interest rate refers to a car purchase method provided by Cadillac brand in a specific promotion. This means that if you buy a designated Cadillac car, you can enjoy the special treatment of 0% loan interest for a certain period of time (usually five years). Usually a down payment is required to buy a car, and the rest is paid by bank loans. According to the usual car loan interest rate, a certain percentage of loan interest needs to be paid during the loan period. However, Cadillac's five-year 0-interest promotion special offer allows you to pay no extra loan interest for five years, just pay the installment repayment on schedule. The purpose of this promotion is to attract more consumers to buy Cadillac cars and provide consumers with more economical and convenient ways to buy cars.
