1. car purchase. This is a must. If you don&;t give it, you will rob the car, haha. 2. The purchase tax, which must be bought after buying the car. If you don&;t buy it, you won&;t get a license. 3. compulsory insurance, this must also be bought. if not, you will not get the card. 4. Commercial insurance, you don&;t have to buy this, but the amount of compensation for compulsory insurance is very low. It is best to buy it just in case. Usually we need to buy: car damage, three, theft and exemption. As for the seat, glass, scratches and other risks, don&;t buy it. 5. Mortgage fee. If you are a mortgage, this fee will usually be charged in 4s. This fee is unreasonable, but if you don&;t give it, the store may not sell you a car. 6. Renew the deposit, usually in the first year, and 4s will force insurance in their store, because this rebate is more, and 4s is profitable. Some 4Ss will also require you to buy insurance from them in the second year or even the third year. So I ask you to give a renewal deposit. If you buy insurance in other places the next year, this deposit will not be refunded. If you keep buying in their store, you can refund it after the contract period expires. 7. Impose decoration fee, you must buy a certain amount of decoration in the store, such as film pasting, navigation and other additional products. 8. Out-of-library fees, file management fees, and so on, some expenses for independent names. 1-3 money must be given, and 4-8 money can be negotiated with 4 S. Therefore, when we buy a car, we should not only look at the discount offered by 4s, but also ask them to give you a landing price, that is, the final cost after all the expenses are added. Compare several stores to see who has the lowest landing price and where to buy it.
