Vehicles & Customs

We'll probably fly down to Zihua once again, but has anyone had experience driving their own vehicle down on a 180 day tourist card, then flying back home for, say, a week or two around Christmas/New Years, then flying back down, and finally leaving Mexico with the vehicle by or before the expiry of the original 180 day tourist card?
I know that when you enter with your vehicle, both the window sticker and Temporary Vehicle Import Permit show the final date by which the vehicle must leave Mexico.....and the paper "receipt" you get when the vehicle leaves Mexico shows the dates the vehicle originally entered and left Mexico.
Would there be any problem with Customs or Immigration at the Zihua airport, either when leaving Mexico for the trip home, or arriving back in Mexico a week or two later?
How about when finally leaving Mexico with the vehicle? The attendant removes the window sticker, but I don't recall them asking that we surrender the tourist card. We've always walked across the road, (at least at the Nogales crossing) to surrender our tourist card and get our passports stamped to show the exit date.
Someone suggested we apply for a Residencia Temporal, but that's too much bother....and expense.
Any advice would be appreciated.
