Thanks to all who followed my repaint question post and provided feed-back.  Here are some screenshots of the final product.  Please feel free to comment.  Once I get the CFG entries finalized I plan to upload.

It is a -200.  Mexicana had very few -100, but they did have some with these colors.  I think I might try and paint a -100 with the same color scheme just to see if the paint kit for the -100 is the same as the -200.  As I understand it 727s was all Mexicana had for significant period of time (at one point it had the "most modern fleet" of any airline during that time).
