4 years ago I got my '77 NYB in Ontario into the US (Buffalo). I went over the Border Passport in hand, purchsed the vehicle.went to Motor vehicle dept. in St. Catherines. The guy I bought the car from met me over there and he did all the documentation for me while I waited in the lobby. We parted company, I stopped at a friends place on the way back to the Border, he followed me to border and customs. It took about 20 minutes total including wait time. All told it was a good experience! Of course it was a pain in the *** getting it liscenced in Iowa....They didn't trust the documentation from Canada, but I prevailed!
