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.

但谁知道，自己在开了这辆车2个月不到，自己的汽车就无法在路上正常行驶了。车主无奈，将车开到原厂检查，多花了3万多才将车子的毛病完全排除！要知道，汽车的零部件是很多的，这些零件也要有专门的人士选用和装配才能让汽车健康的运转。如果被一些小店用一些次品零件来装配车辆，拿这辆车肯定是被毁掉的。

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.

像气门弹簧，他的作用就是要保证汽车发动机的震动密封性，让气门回位。劣质的气门弹簧会让发动机损坏之余，也会让气门的连接部位遭到断裂。而这样精密的零件在市场上的价格绝对是很贵的，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.

很多车主之所以选择街边的汽修店，是因为想省下几个钱，毕竟现在生活不易，大家都是懂的。但是这样省钱却未必给自己带来很好的效果，毕竟车这东西一上路，万一中途出事了可是非常危险的，再说，如果自己换的是次品零件，那么后面又要再换一次，岂不是得花更多的钱了吗？

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，大家在自己的车子遇到大毛病的时候，更好还是去4S店维修吧，毕竟那里的零件都是原装进口的，而且售后有保证，出事了只要拿相关的证件去说理还是可以把问题解决好的。更何况车子本来就是消耗品，如果车子有问题时间肯定是要把问题彻底修好，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.
