Maybe another thing is important as well: in terms of history of the car an import might be somewhat more prone to dodgy actions, such as changing the milage or not reporting on damage caused by an accident.
Here in The Netherlands, we have a very good system to register milages over time, accidents etc. For most imports, there is no register or it is not possible to look into it as a foreign party. So beware that if you buy an import, something might pop up! The safest way is to see if you can buy an import with fully documented history and/or let a Honda dealer have a look at it to see if there are any inconsistencies.
That being said: the Jazz Hybrid is a very good car without any major flaws. Afaik mechanically it will be no different. The normal (non-hybrid) Honda Fit (for US and Canada) is a bit different: only as 1.5 with different emission regulations and somewhat different bodywork too.
