The EPA rules only concern emissions, and being 21 years old is helpful for the car not having to suffer through that inspection.....BUT, don't forget the Department of Transportation requirements which pertain to cars less than 25 years old I'm not sure whether there are differences in the rules for importing from Canada vice the rest of the world, but here's what the bottom line was two years ago when I brought mine home from Belgium:

If the car was not originally manufactured to US specs, you have to go through a Registered Licensed Importer, which involves posting a bond at 1.5 (?) times the car's value, then modifiying all those things that aren't U.S. "compliant" before being able to send it through customs and taking possession. I'd guess you'd be looking at a starting figure of around $5k for the RLI's "services" and the mandated changes (fugitive emission boxes, US speedo, etc.). Worst part about that is you likely don't want those mods, otherwise you'd buy a US spec.

The other potential problem is that the Euro version Jalpa is not listed in DOT tables of Euro manufactured cars as being "substantially similar" to their US versions. This is THE prerequisite for importation of cars less than 25y.o., as the car has to be brought into US compliance, but DOT only considers cars on their list. This should be obvious to DOT since there are Euro spec Jalpas in the US, but I wouldn't count on it. I also wouldn't consider it impossible, and would bet that a call to the appropriate office at DOT (phone numbers available on their website) would ultimately yield success. Would probably require a lot of patience and diligence on your part, I'd bet. Maybe someone with a Euro spec Jalpa could provide you a copy of their DOT papers for an example for the DOT officials to guide them through approving your Jalpa? Mine would be worthless to you, as my car was specifically allowed under the following means.

Obtain a letter from the Factory Designated Agent in the US stating that, "... (the car) was originally manufactured to US specifications except for minor labeling differences....." This simplifies the process to one each EPA and DOT forms, and the attached DA letter. I don't know, however, who the current Lambo Designated Agent for the US is....

You can very likely get a car through with an RLI, if you want to spend the money, or you could wait a year at a time for the model year you're looking for. That last one doesn't sound like a viable solution when you want one now, though.

Let me know if I can help you navigate through this.
