I wouldn't bother unless you really really love your car! If I were you I'd sell it and buy a newer better car in the US.
Now could be your chance to buy some big V8 powered monster such as the Camaro, my curent favourite especially in black. Cars are quite cheap here. You can get a top of the range 6.2L V8 Camaro with 426 bhp for 42k CAD.
I can't get even the basic parts for my car in Canada, plugs, oil filter, brake disks pads. Everything has to be couriered from the UK at great expense. I've found plugs in the USA and I think FRAM makes an oil filter but it would hav to be special order.
Your car will be RHD which is okay most of the time unless you want to overtake anything on a single lane road.
There are no specialists, you've have to trust the car to someone who's never seen one before or do the maintanance yourself.
Insurance will be expensive as it's a non US car.
Think about the costs involved in replacing the windscreen or bonnet.
I took mie with me because I'm nuts
