Regarding the car loan of 10W, it should be said that it is not suitable for buying a car by loan. Generally, the car loan is only three years, and the annual interest rate is close to 5% or even higher. It is better to save these interests for another six months (if you invest, it will be less than six months). Moreover, car prices will only fall, and used cars will depreciate quickly. The rebate is mainly commercial insurance, not compulsory. The business rebate is 10% of the premium, and more. No more than 15%. How much they will give you back depends on what you say, just like buying food in the vegetable market. You say others' is cheaper than yours. Just don't exaggerate. In order to get business, I may give you more.
