Import of project Vehicle

69signetv8,
Although I haven't done it this is what I have learned from asking many questions when I was looking. It must have a clear title, you have to wait 4 days after you purchase it to get it across the border, you must have a bill of sale and you will have to pay the sales taxes that apply when you come across. (that can be billed to you)
One thing that I never did get a clear answer on was the A/C thing. They are real picky about it. They wouldn't give me a clear answer when I asked if it made a difference if the A/C was off the car.

Hope this helps

Jack
