Can I hypothetically import an American Crown Victoria into Japan? (This is a question but there’s no flair for that)

I don’t live in Japan but in the future I would like to and I was wondering if I could hypothetically import an old Ford Crown Victoria police car and actually have a US police livery on it. if i can, what would be the process to import it? (also this is all if i hypothetically move to Japan and have the money.)
