One has to interpret what they mean in the document that specifies the Importation Permits from SAT.
Roughly translated it states that you can only get one Temporary Import Permit in one year, that you can take the vehicle out of Mexico and back in as many times as you want within those 180 days and until the 180 days have been used up, this is written in the SAT document from SAT on importing foreign vehicles in to Mexico.
As you know Mexican law makers and lawyers love to use a lot of convoluted words to say something very simple so that they only can interpret the law and charge lots of pesos for a simple answer, too many lawyers steering the pot.
moisheh, I hope you read and understand Spanish, this is taken from SAT document on the internet.

Go to Aduanas and scroll down to vehiculos
The law for the Mexicans importing vehicles applies the same for foreigners that have a TIP of 180 days
