Car breakdown is stressful
The fun turns into distress when a car breaks. Fixing a car today is very stressful, time consuming and expensive. It takes days to fix a car. Indirect cost of time lost from work or school, the anxieties of not knowing what went wrong and how much it will cost and renting a car or finding a ride, all can add up to an unbelievably high number.
