I have some wheels arriving tomorrow - dont forget to factor in credit card foreign currency conversion. works in at around 2.5% on my card.
Make sure its marked as made in the USA. you will get a discount on duty. I had to send a statement to fedex this morning describing the good, and stating they were made in US from US sourced materials. Duty and gst (which you have to pay if total including shipping is over $1000) was going to be $419, and dropped to $269 after I sent the statement through, so from my working out duty dropped from 10% to 2.5% with the free trade stuff factored in. Also, and Im not sure about this, say its for a 1965 cobra. I got the impression from the customs broker guy at fedex that the rate was less for "old" car parts - someone else might be able to confirm this.
Cheers.
