I think I got it...

Ok, here it is. I just remembered this. We can use the "Show and Display" law. From what I understand it works like this...we have to explain why the car is significant to automotive history or something to that effect, then how many miles a year it will get used for(I think like 5000 max), and a few other details that I cant seem to remember. I read about this in Excellence, a Porsche mag. That is how people are finally getting the 959 into the country to drive on the street. If anyone knows anymore, let me know. Im gonna try and find the issue of Excellence that this information was in.

:D Too bad the Skyline's not on the pre-approved list. :(

Sorry, it has no technical significane like the F1 or the 959.

I have tried the show and display - won't work. Sorry.
