The Micra is sold in Mexico as the March. It is, indeed as you said, the model under the OLD 2007-2011 in USA Versa (Tiida) sedan which is still made and sold here. The new Versa, 2012 to present MY, is the next model up from the old Tiida.
IMHO, the March is not really such a nice car. It shares a shorter version of the same platform used in the new Versas, but it is narrow, cramped, cheaply-finished and rides like a buckboard. (Other than that, Mrs. Lincoln, how did you enjoy the play?

)
BTW; the 2013 Versa sedan, same one you have in USA, is quite upmarket here, even the base version comes with electric windows, locks, A/C and other fancy stuff standard. Uplevels have automatic A/C, nicer seat surfaces, more color choices, fancier stereo, etc.
Are all 2013 Versa sedans all so fancy in USA?
