My plan is to import a 1991 GTR sometime in the beginning of 2016. After winter most likely lol. I know i have to get an HS7 declaration form & EPA 3505-1. So my questions are. How much is the tax I'll have to pay & are there any hidden fees? Also I know the undercarriage of the car must be pressure washed so there's no Canadian dirt on it. Will I need to obtain any sort of Canadian driver's license or insurance in Canada to drive the vehicle back to the US? I know I'll need a passport but will I need any type of Visa to go to Canada? Also is there anything I haven't mentioned that I need to know before I go to get my dream car?
