There was a car owner who bought an Audi. Due to the recent poor business and lack of funds, even his car "broke down" on the way. Helpless, I had to send my car to a maintenance shop on the street to replace a series of parts such as valve spring and gasoline door seal (it would cost 10000 to replace them in a normal 4S shop). However, this auto repair shop only needs 5000 to complete the whole process, which makes Audi owners feel very happy and think they have found a bargain.

但誰知道，自己在開了這輛車2個月不到，自己的汽車就無法在路上正常行駛了。車主無奈，將車開到原廠檢查，多花了3萬多才將車子的毛病完全排除！要知道，汽車的零部件是很多的，這些零件也要有專門的人士選用和裝配才能讓汽車健康的運轉。如果被一些小店用一些次品零件來裝配車輛，拿這輛車肯定是被毀掉的。

But who knows, I've been driving this car for less than two months, and my car can't drive normally on the road. Finally, the owner was helpless and drove the car to the original factory for inspection. It took more than 30000 to completely eliminate the problems of the car! People should know that there are a lot of special parts and components for automobile assembly and operation. If some small shops use some defective parts to assemble the vehicle, the car must be destroyed.

像氣門彈簧，他的作用就是要保證汽車發動機的震動密封性，讓氣門回位。劣質的氣門彈簧會讓發動機損壞之余，也會讓氣門的連接部位遭到斷裂。而這樣精密的零件在市場上的價格絕對是很貴的，要想便宜根本不可能。

Like the valve spring, its function is to ensure the vibration tightness of the automobile engine and return the valve. Poor valve springs will not only damage the engine, but also break the connecting parts of the valves. The price of such precision parts in the market is absolutely expensive. It is impossible to be cheap.

很多車主之所以選擇街邊的汽修店，是因為想省下幾個錢，畢竟現在生活不易，大家都是懂的。但是這樣省錢卻未必給自己帶來很好的效果，畢竟車這東西一上路，萬一中途出事了可是非常危險的，再說，如果自己換的是次品零件，那么后面又要再換一次，豈不是得花更多的錢了嗎？

Many car owners choose the garage on the street because they want to save a few money. After all, life is not easy now, and everyone knows it. However, saving money in this way may not bring good results to yourself. After all, once the car is on the road, it is very dangerous in case of an accident on the way. Besides, if you change defective parts, you have to change them again later, wouldn't it cost more money?

所以，大家在自己的車子遇到大毛病的時候，更好還是去4S店維修吧，畢竟那里的零件都是原裝進口的，而且售后有保證，出事了只要拿相關的證件去說理還是可以把問題解決好的。更何況車子本來就是消耗品，如果車子有問題時間肯定是要把問題徹底修好，以免留下后患。

Therefore, when you encounter major problems with your car, you'd better go to the 4S store for repair. After all, the parts there are imported with original packaging, and the after-sales service is guaranteed. If there is an accident, you can still solve the problem by reasoning with the relevant certificates. What's more, the car is a consumable. If there is a problem with the car, it must be completely repaired at the first time to avoid future problems.
