USA car in Mexico

Thank you for both answer and additional question.
I’m trying to compare the situation to Canadian snowbirds driving their Canadian car or RV to Florida or Arizona for 6ish months every year. True that really few (none?) may have green cards so they are « tourists » in US per se.
But if I want to do the same from Canada to Mexico, would it be better to keep a temporary resident status instead of getting the permanent? Though I think that after 4 years you are automatically switched from temporary to permanent….
Or another option, having no Mexican residency status, being only a Canadian tourist driving his car, but with the 6 months limitation in this case…
In fact as of today we just don’t have a car in Zihua, we take taxi and buses. But as rentals are not easy nor cheap to get, I was wondering what my best option was.
