It's better to go to a 4S shop to maintain the exterior of the car.

I have been engaged in 4S shop maintenance for several years, and I have also worked in a small facade outside. Let me talk about my opinion here! I operate Dongfeng Citroen and Dongfeng Shen Feng in 4S for a long time. You'd better go to the 4 S shop during the warranty period. General maintenance of domestic cars is: engine oil 100~200, engine oil filter within 50, carburetor cleaner (accelerator cleaner) 10~20 yuan, working hours 100~200! It will be fine! Generally, it is enough to maintain it at most twice a year, and it doesn't cost anything. Just some major maintenance (3W, 5W, 6W km, etc. , different cars, different kilometers of maintenance) will cost a lot, and the working hours will double or double. At the same time, all oil (engine oil, steering oil except electric) and gearbox oil may be delayed automatically, and a small amount of water can be added to brake oil (antifreeze) in summer, which is not a big problem. . Keep the price at 1000~2000! After the warranty period, I will insist on going to the 4S shop for maintenance. Remember the following points: First, you are not a professional maintenance worker. Don't think you know a lot or you are an old driver who has been driving for a long time. Tell me what to do during maintenance. Ask the repairman privately if you have any questions, instead of telling the repairman what to do. Maintain due respect. You are a consumer, but he has your car, and you don't even know what to do, so you. Second, don't trust any additives, and don't be recommended to buy any additives by the front desk or maintenance personnel! That's useless. Third, the price of accessories in 4S stores is unified nationwide and can be found online. Their profit is less than 20%. They mainly earn working hours, but not much for accessories. Some people will say: Bullshit! I bought it outside. It's much cheaper than a 4S shop. I bought it from some acquaintances. Then let me ask you, is the original factory he said the original factory? Do you know what the original factory is? You don't know! ! ! Looks the same as the original factory? That's a lie. Small factories outside make money by selling spare parts, with profits as high as 200%~500%. Because they are all made by deputy factories, the purchase price is low, so I don't charge you for working hours, which captures your love for cheap! Believe it or not! I have nothing to do with the maintenance industry now, and I have already washed my hands of it! Never mind what I'm holding.,,, Oh. . . Finally, I'll sum up one more sentence: the car is always getting worse, you know! The service life of auto parts is generally 4~6 years. After this time, there will be more and more car problems. It is recommended to change hands at this time or later to buy a new car. The above is just a personal opinion, and there are many shortcomings. Please forgive me! If you agree, praise one. If you don't agree, keep it and laugh it off!
