Myth #10: If it Ain’t Broke, Don’t Fix It
This is perhaps the very best car tip ever, no myth about it.
Most experts agree that this is a good theory. You can probably recall watching a friend go into repairing things that didn’t seem to need repairing and make himself a bunch of problems. It’s still a good rule of thumb, provided you stay up with the maintenance. Wait until the car gives you telltale signs of problems then respond.
