qtlq9111 is so right. If you live here, use the systems as they are designed.
Yes. if you alternate your residencies between temporary and permanent, you can get more time driving "out of country" vehicles. Is it that important?
When we settled in here, permanently in our home, it made a huge difference as to how we felt about things. We no longer have any need or desire to go north of the border.
Did we expect that? Not really, but we have found that our outlooks and thoughts on life have changed dramatically living here. It's really really good.
That's all very personal and obviously varies between people. We are extremely happy here and are so glad we made the decision to immigrate to Mexico. For us, it was a great thing and we are thrilled with our decision.
For others??? It's a very personal call and hopefully you will make the decision that will make you the happiest!
