Buying & Selling Vehicles across the Canadian - USA Border

LOL- the Canadian boys challenge you a bit to see if you waver on your price. A copy of your wire transfer or MO is enough but they seem to pick out the first timers to hassle a bit. Its been a while since I have gone into the passenger car side as I usually have a trailer load so I preclear them for import.
At Lewiston US customs- the young lady will ask for the email and I have seen her make people wait because they leaned on her counter. I prefer to deal with the man.
Port Huron is busier and more professional with a more thorough inspection of the imported vehicles.
