from what I have found the vehicle will not be the issue, its about to be 30 years old which puts it in the classic category of allowable import.
  I don't intend to drive it down, it can't be done in a single day and it would be a high target for thieves!  I will ship it down, keep it inside our compound and only use it for running around exploring.  we will have a nissan sentra for trips into merida.
  I know I should just give it up but I have had it a long time and am irrationally attached (Of course I am still waiting on a shipping quote which may unattach me)

Know the feeling, I had a 2005  S-4 Audi. The last model with the R8 engine. It would never be legalized , so I drove it back and forth for 2 years.
Things got taken off of it, and finally a big storm passed through and it sort of drown, the Mexican insurance stalled it wouldn't cover it, the seats rotted while I waited. the insurance didn't call or say  it was a write off so they  fixed some of  it after it sat 3 months in Merida.

The car could have been restored , and it was partly restored, but I took it to the states ( drove it) and sold it. The leather seats were shot but the core of the car was still good. I lost half of the value of the car. But have no problem with my Mexican Mazda. Cops don't stop me , I found a garage and all is well.
