Import duty is max 6.1% on non NA built cars. There is no reason to hire a broker unless you're shipping the car. Here's what you do:
• Find a car, have it inspected by a local. If it looks like the one, agree on a deal subject to inspection. Arrange for your insurance carrier to cover you should you buy the car (most will cover you for 2 weeks for nothing if you have cars covered already).
• Have the owner (or get a copy and do this yourself, as I did) Fax the ownership title to the US Customs office where you will bring the car through (the actual border crossing) a minimum of 72 hours before arrival there. Follow up to ensure it was "cleared" (not stolen, no liens etc.)
• Travel to see the car for yourself. If it is as you expected, pay for it and head for home (with a local temp road permit arranged by the seller, or tow it on a trailer as I did)
• Show up at US Customs at border and get them to stamp the ownership title as "Clear" to export (no charge for this service)
• Drive to Canada Customs. Declare the car, go into the office and show proof of payment (copy of bank draft, copy of bill of sale and "stamped" ownership title. Pay GST and the duty (based on the Canadian amount paid at that day's exchange rate).
• Drive home and enjoy your new Pantera.
I did this with my GT40 and the importing part took me 20 minutes total (at a slow border crossing). Not worth $400.00, since the Customs people will help fill out the form for you (it's one page and nothing tricky).
I understand this sounds scary, but trust me, it's not as scary as owning a 35 year old Italian car...
OR... get Julian to buy it and bring it with him when he moves to Calgary!
One other thing... don't buy a car with messy ownership issues (not titled in the current owner's name) — Derrick can tell you what an arse-pain that is...
