Apologies if this has been asked before(I'm brand new here...) OR if I'm under the wrong section >> did a search which showed up nothing. Does anyone know what the differences are in a US Spec Model S vs. a CAD Spec unit which prohibits a US unit from being imported into Canada as a used vehicle under RIV. I'm quite familiar with the car - have driven each with no discernable/noticable differences in displays, ride height, etc. I'm told there are a few software differences and one hardware difference. Many thanks!
