Hi John..... yes there are a lot of limits for you to bring the car directly from tokyo to italy....i dont exactly what... but i think that is impossible to register directly a japanese car here... the best thing is to register as EU car your skyline in UK or Germany and then you'll register your car in italy without problems....
Hope can help ;-)
im considering moving to italy, and i own a 96 skyline. i currently live in tokyo and i'd like to know if there were any modificaytions, restrictions, etc about bringing the car with me. any help would be greatly appreciated. thanks.
