Thanks everybody, Todd, Scott, Ben, etc.
Like I had mentioned before I have been in touch with the NHTSA but have not received a reply from them. I have found a street address where one is required to write (like anybody still writes) to request for consideration for Show and Display status. The Ultima Edicion satisfies 4 out of the 5 requirements for consideration, the one it misses is that there are (or will be) more than 500 autos produced. I do believe that could be worked around. I might have to write them a letter and put it in the mail.
Now, Miguel at Btlmex has written back, and mentioned that the $13,800 includes purchasing a new Ultima Edicion in Mexico, and completely transfering it to the reconditioned pan. No taxes, because I'm not in Arizona, and about $500 to ship it to WI, or I can pick it up in Tucson. What worries me about this process are 3 things: -Would the car loose some of its value because it wouldn't have the new pan (I would think that since they will be the last 3000 cars made, the registration number would be something collectors will be looking for)? -How would pulling apart a car, and installing it in a reconditioned pan affect the performance of the car, particularly in the long run if at all? -Would it be possible for me to save (have it shipped) the pan with the registration number, in case I ever want to transfer it back and maybe use it or sell it back in Mexico or anywhere else?
I have asked Miguel the above questions, and if anybody has any comments (including the comment about keeping it registered in Mexico that you can see below), they are very welcome.
