Problem: These cars have to be manufactured to meet NA standards. SAAB yes. Skoda probably yes as they are VW platforms. Renault and Fiat have not sold cars here for a long time and their cars probably would need re-engineering to meet the standards... talking crashes here not emissions. This takes some time to do and is expensive. Unless the USA has changed its rules it could be done onshore in the USA for the USA market, but Cdn rules state that this sort of thing must be done by the ORIGINAL manufacturer which might pose a problem.
I hate being a wet blanket on these things as I'd like to see more Eu cars sold here, but I don't see Canada changing its rules for a few Saturn dealers. They might change them to allow some Chrysler badged Fiats come in but I doubt that as well.
