Hopefully this information is current, the only date given is in 2013. I hate to be the skeptic, but we've learned a lot since we have moved here.
Since you are planning to get your temporary residency, why don't you just buy a vehicle here? They are significantly less expensive than they are in the US, and tend to have very low mileage, depending upon where you buy them. We are on our second vehicle. The first was purchased to pull our 8 foot cargo trailer *Mexico plated) to the US and back, and the second when we realized that the Durango was way too big for town and sucked gas. Love our Escape and the dogs fit nicely.
Just things to consider.
