Go north bound on # 23 towards Guadalajara. After you pass # 35 (by Los Burritos restaurant) you take the first returno and head southbound on # 23. Its about 1 km to the west bound entrance to the Macrolibromiento.
We (Canadians who are RP) obtained a visa from the Russian Embassy in Mexico City 4 or 5 years ago.
Our travel agent had arranged for a facilitator from Mexico City to obtain the visas on our behalf.
I can't recall the cost.
Our agent, Edgardo Cedano Cardenas, went and was told that they were still waiting for the "health certificate" before they could accept insurance companies.
We have purchased them in the past and have always had to ask as they are not where you would think where they should be.
They were limited in colour to blue and black.
This has been discussed over the years on the local boards.
It is my understanding that you can only bring your Mexican plated vehicle into Canada if you are an registered "non resident" of Canada.
