I disagree with the reviewer's statement that there are no substantial differences being reported over an 11 year period. Because of our interest in visiting and living in Mexico, I own three editions (including the 1988 and the 1999 copies). I've found each edition extremely comprehensive and appreciate the updated material provided in each. Like any guidebook, Choose Mexico provides comprehensive information about living, retiring, and doing business in Mexico. We have used it extensively during our yearly semi-retirement visits to the country. The basic facts in any guidebook do not change from year to year while new regulations and changing economic are dutifully reported. I certainly don't expect the authors of a guidebook to present the same facts in a different form for each new edition. It's a guidebook, not a novel! I would rate Choose Mexico as five stars for their complete and entertaining guidebook on living in Mexico.
