Buying & Selling Vehicles across the Canadian - USA Border

Why you have to present the car to the export customs?
In European Community we can cross borders without any taxes, if we sell a car to outside EC the customs are completely desintereted. Only thing you have to declare are military equipments.

And importing is easy, too. All I need is a title with a VIN and the sales-contract. Calculating custom-fees lasts maybe 30 minutes.

I thought trading between US and Canada would be much easier...

You would think it would be easier....
They want to make sure that the vehicle you are importing is cleared and not stolen. and obviously they want the tax money...
I've done this a few times,US to Canada, and make sure you have all of your documents proof of purchase and a receipt...they've even been on my ebay account just to verify the amount paid to the seller.
