There are a lot of components connected to the car with screws and bolts. They must be assured enough pre-tighten function, but not too tight. If they are screwed too tightly, the connector will deform under the external force, on the other hand, the screws will be stretched, caused slide and break.
No charging to the storage battery-shorten the service life
The first time charging of storage battery can have a huge impact on its service life. If you don’t charge and just add some water for it, the service life will be shortened; direct charging will also shorten the life. Usually the first charge will be after adding the electrolyte, charging by small electric current about 1 hour and it will be ready for use.
Install new equipment randomly-affect driving safety

Some people love their cars too much to drive them, they only drive on holidays. In fact, it harms the car a lot. The engine and transmission box will get rusted directly contact with the air, and the storage battery will be short-lived due to a long-term natural discharging. The best way is to drive the car every few days and for 30-40 minutes per one time. Besides, frequent short-distance driving harms the car as well.
