Bus line in El Salvador-worst ever!

I would just like to warn all those tourists who plan or are about to go to El Salvador, not to rely on buses as means of transportation, or getting around the country. I had such a very bad experience with it, and I blame it on the agency I booked my trip with, so, I think that others should be aware of this too, in order not to make my mistake.

Would you be so kind to give us more information about your experience? My husband and I are planning a trip to El Salvador, and we planned to rely on buses as the main way of getting from one place to another, we even inquired about the bus lines, prices and everything. Based on what we read, there is nothing wrong with it.
