Not exactly a confidence builder, our driver stopped after we had driven only about 2 miles and added oil to the engine. This was on our way up a mountain on a dirt road! This was a Chinese-built bus called a Coaster. Most of the buses in Central America are former US school buses, but the Chinese have imported a lot of these 30 passenger diesels for the express routes in major cities. They are not comfortable for large people, but they move a lot of folks every day.
