I've been searcing for ways to get from Mexico City to Los Angeles by bus, and so far the only thing I've found is Greyhound, which, combined with partner companies, takes you to LA with changes in Chihuahua, Tijuana and San Ysidro for USD 235 (which cannot be bought online)
Are there any other companies offering through tickets between Mexico City and Los Angeles (possibly with interchanges)?
(no, I am not interested in taking the plane)
