Buses are the universal travel system for Mexicans, so buses will get you anywhere you go. The service and comfort are not always great, so it pays to know your bus line, its record and equipment. But if you study it and try it, you may like it. And on trains, particularly, you will see places barely reachable except by walking or horseback. You can take your car into Mexico, if you conform to the red tape at the border, love your auto that much, and want to have the best method of seeing all of Mexico's great scenery.
Many experienced vacationers take cars into Mexico regularly.
The problems of bringing your car along to a home in Mexico lie in massive regulation and strict controls on what you can do with your car. Unleaded gasoline is easy to find outside the big cities and repair parts, while usually available in time, are more expensive than in the U.S. Labor, of course, is much cheaper and this often more than balances out the cost. Many believe you are wiser to buy a Mexican-made car than to take in a U.S. model. American, Japanese and German companies manufacture cars in Mexico and sell them there. These cars are not much different from those sold in the U.S. and Canada, but most buyers think them reasonably serviceable and there are fewer problems finding repair parts than with foreign cars.
