i’ve done it before (thought not an S13)
this is for cars over 15 years old - it’s a different process for newer cars
the main thing to remember is to fax a copy of the signed ownership to the US side of the boarder you’re going to cross at least 72 hours before you cross with the car.
you can go about this a few ways:
- go down twice (once to view the car, once to pick it up)
- stay in the states for 3 days… though this presents problems with plating the car to drive it back
- buy the car sight-unseen and have the previous owner mail a copy of the ownership to you for you to sign, then fax to the boarder
after you’ve paid for the car and faxed your ownership to the boarder and switched insurance over, you’ll have to get a temp permit for it… i was hassled about it a bit due to the fact that it’s an ontario temp permit on a car with a US title, as far as i know a temp permit counts just as well as a proper plate… this seems even more true with the new temp plate system.
so now you have your temp permit, insurance and have waited 72 hours from faxing the ownership. time to drive the car back.
pretty straight forward - once you get to the boarder, tell the US crossing guard that you’re importing the car to canada, he’ll tell you to go to a building there. go where he says, tell them that you’re importing it, they’ll ask you some basic questions and fill out a form for you.
you then go to the canadian side of the boarder and repeat the process, you may have your car inspected at this time, depends how sketchy you look… i look like an average person so the car i was importing didn’t get searched, however my friend that drove me down in his car always looks like he’s up to something, so his car was searched for 20 minutes or so. other than that, you’ll just have to pay some taxes and the A/C fee if the car is equipped with it. the car i imported didn’t have A/C so i’m not 100% sure where you pay the fee, i believe it’s at the boarder.
once you’re done there, take it home, the hard part is done. now you have a time limit (i forget the length, i believe it’s 90 days?) to complete a safety check at a canadian tire. before this check you may have to modify some things on the car to comply with canadian laws such as airbag stickers, day time running lights, etc. check with the RIV for what needs to be done to your specific car.
next up, get your e-test if the car is an '88 or newer and then plate it, you’re all done.
it’s actually a fairly simple process as long as it’s an older car. from what i’ve been told it’s a bit more complicated for cars less than 15 years old, but still not that bad.
feel free to ask me about it if you need some more info.
