car registration required in Mexico?

hello. i drove a mercedes into mazatlan in 2007. At the time it was connected with my FM3. i basically never drove it and after i applied for and got my FM2 because i was not able to drive "foreign plated car" with my type of visa and if stopped and discovered could have my car taken from me permanently. I decided last month to drive it back to the states because i could not afford what it would cost to nationalize that car(i am up for permenant resident this July). I did receive a 6 day permit to drive the car(from Aduana authorities for leaving Mexico)and a one time pass(from the US to drive to a DMV and register it pronto. When i got to DMV they asked me for 2 things. 1. Proof of Mexican registration(wow...i was under the impression that your car went with your FM3 and no one ever asked me to register it in mexico)and 2. Exit forms from customs when they take your sticker off at the border(i have gone through this process several times and never received any forms). DMV gave me some samples from US customs(form #'s 7501,3461,6059,3299,3311 all coming from homeland security and are not applicable to my situation). Also i was given some sample registration forms from Mexico(from DMV ) which all refer to nationalized cars which mine was not. DMV is requiring that i pay back registration here in Calif for 2009-2013 basically $585 plus late fees..around $750US if i cannot come up with these forms. The bottom line is i had a car that was in "non use" for those 5 years in Mexico .The DMV states that i needed a non-use permit from the US for 2009-2013 if i want to avoid back registration even though my car was in Mexico(huh?) I cant for the life of me see why i should pay the US any money for this time period when my car was inactive in Mexico and not on any road. Help.....I would appreciate any expert advice along these lines. thanks in advance

yes and my ex(who gave me the car)declared to the DMV that it will be registered elsewhere. I thought the registration was connected to the paperwork that entered my car into the country. Mexico did not require me(nor ask me, or send me forms to fill out )an when i put it out to pasture (not driving on the streets anywhere) i felt it the proper thing to do. When i made plans to enter the US with it again the US DMV were notified that the car was not registered and i was issued(a friend did it for me) a "one trip permit", which i presented to the DMV at the time of trying to register the car. They did not tell me to get proof of registration in Mexico or some paperwork from US customs at the border at that time. Why not? So i am still looking for solutions here....any help?

Boy, you sure read a lot more into this thread than appears anywhere in the OP's responses. I think the OP is looking for a solution, not what looks like an "I told you so" bashing that assumes far too much.
