BIG congrats!
I know you have been researching and reading up on the forum for last few months. I really wanted to see the 19" rims in Australian Zs. Hopefully Nissan will bring them next year (or you can convince me to sell mine
)
I didn't get those "protection" coverage. I personally do not think they worth it but I never bought them with ANY of my cars. I will let other members give you true feedback on it.
Good luck with everything.
