My tip - don't get the woman inspector lol. She spent a good 20 minutes just searching for my engine number. She was so rude!
But yeah, make sure stuff like:
-Tyre must have 80k/h written on it
-This might not apply to you, but I needed the GTR manual in my glovebox!
-Tyres are correct size as per tyre placard (again, might not apply)
-Baby restraints are in
-Seat belts working
It's pretty easy to pass
