There are always people who want to mod their cars. While I doubt a lot of people are going to be into MAJOR mods with the iA, some will.
I think most will be suspension and power add-ons, to take advantage of the light weight of this car. Some will turbocharge or engine swap or more, however I am pretty much sticking to bolt-ons (which I consider to be relatively minor mods).
The discussion on swapping the front end is just a thought. And in all honesty, i doubt I would ever go through that much trouble to import a front end, paint, etc.. The steering wheel or higher quality interior pieces (leather steering wheel, etc) on the other hand, helps make up for the lack of trim options the iA has in the US.
