friend of mine crossed the border with a 69 camaro that he had bought from the states for 16 large...upon crossing the guards refused to acknowledge his bill of sale and what he payed for it, and instead charged him taxes on what it was "supposed" to be worth, 32 grand...hes not even a younger dude either, well to do middle aged man not suspicious at all and super friendly too...proof that being a nice guy at the border gets you no where since its all up to them
