That's clear across the country from you, so tack an extra thousand or so onto the cost of your conversion for the shipping costs.
About the import paperwork: The Canadian Registrar of Imported Vehicles website SWEARS it's not that hard; ) Really, EV conversions tend to fly under the official radar because they don't SEEM, to the uninitiated, any different that the original car. An electric Chevy S-10 looks just like a gas-powered Chevy S-10. The VIN is the same. The safety equipment is the same. I find the insurance companies and the DMV down here in the States treat a conversion exactly like its gas-guzzler twin. So...as long as you look at the RIV's list and make sure the car is on the approved list in it's GAS form, it should be a piece of cake.
I guess if it were me, I'd be taking advantage of the weak US dollar right now. You could get yourself a really good deal!
