I really believe that when you are a driver, you should also know how to repair, even a little, just to be safe if you experience a car breakdown on the road, where there’s no one else to help you and the garage is far from where you are.
This happened to my friend few months back. Her car wouldn’t start. She was on the road. It happened on a Sunday. Majority of the shops were closed that even if she calls for a limousine or rv repair, no one will be there to answer her calls.
She was lucky to have gotten hold of another friend who came to the rescue.
