Driving Mexican plated car into USA

My husband and I both received our permanent residents visa and with the visas we are no longer permitted to drive our Tennessee/US plated car into Mexico. One scenario has us purchasing and registering a car from Zihuatanejo, driving that car all over Mexico and back home to the US in the spring and returning for the following season. Specifically are there problems we should consider crossing border going and coming. For example how long can car stay in US? I have added my email and can do a sit down here in Zihua or can phone you.

Have you checked with US Customs, or whatever they're called these days?

Was looking here on the board for help based on first hand experience. Have only talked to recordings and the recorded voice said US citizen can bring car into country for a year, that may be the be all end all I was looking for! I'll take no responses that on one knows anything useful on this single topic.

We also have permanent residency. Have driven our Mexican purchased/licenced car back to the USA twice with no problems. It stayed in the U.S. about six months on each occasion. Just make sure you have USA liability coverage. Our Mexican policy incliudes this and yours may also. If it does not you can buy a policy near the boarder but that will require a Mexican driver licence.
