Not really. If you read carefully, the rules state that cars 15 years old and older can be brought into Canada with no mods needed. Anything younger and it must meet our strict laws (so no Skylines or any other new car like that). And even then, I don't think it can be imported into the US, because I think you have a clause like ours, except the car must be older (I think 25 yrs old).
Basically, what is avaliable in the US, is what's here in Canada and if its in Canada, it can go to the US (and even then we are screwed in some ways, because we never got the F50 and a few other cars like the Toyota MR Spyder). Canadian cars can go to the US, since they have similar and recognised testing certification. A car like a Skyline has no similar certification and you couldn't dream of bringing one to Canada (needs stricter test than what you guys do).
From your post, the only way you could do that is if you're a diplomat (a citizen other than US or Cdn).
