No options, the Legnums are not yet over 25yrs old to be eligible for importation into the US (still got 3 years before it is eligible to be imported). If you did buy one up in Canada, you would need to store it somewhere up there until the month of manufacture of that specific car in 2021 for importation.
Then you need to look at the availability of parts, specifically engine parts as these cars share nothing in common powertrain wise as their USDM Sedan cousins. The VR4s use the 6A13TT 2.5l V6, which is a entirely different family of engines from the 6g7x series.
