The essential car repair kit is the one that fixes a problem that might render the car immobile. It also should be a problem that can happen to anybody at any time. One type of car repair kit that checks both of these boxes is a puncture repair kit. A flat tyre can sometimes completely kill the mood of a trip. Unless you have a spare tyre to replace or a repair shop not far away from you, you will be waiting in the middle of nowhere for hours. And will probably have to pay an exorbitant amount of money to the mechanic as well.
