TN taking my Canadian. Financed Car

Hello guys,

I’m planning to take (not sell) my Canadian car with me under TN status to California.

I want to use it for 3 months to 12 months (Canadian plates) then go to the border to import it to the US officially. Since then I will have already paid for it

Insurance will be Statefarm as I would have cancelled my Canadian insurance (or maybe keep it)

My question is: what do I say/show the CBP officers at my POE?

Thanks guys

Edit: I drive a Jeep Compass 2016 - I can easily get the compliance letter (already in process)
