We prefer 57 through Matehual, arce norte around Mexico City, Puebla, Orizaba etc. Keelhauler has many years more experience than we but we just do not like the coastal roads, Tampico, etc. The only problem with central route is the stretch on 150D between Orizaba and Puebla. Adabatic winds in late afternoon (warm moist air from Caribbean hitting the cold air from the glaciers on Pico Orizaba) can turn the top portion into complete white out as we discovered to our sorrow. Mexico Mike wrote us to always do this portion of the drive in early morning.
