Most of the people importing Japanese cars are not supporting them. A lot of them are not even doing pre-purchase inspections IN Japan before bringing them over. That might cost about $200, but that's $200 that could be in their pocket. They'll bring in any broke, rusty, hunk of shit and someone will buy it, and that's it from them.

And that is a big deal, the other part is simple maintenance. I looked into this and spotted a huge market where, these dealerships do import these keivans, keicars, etc but have no idea about the unique parts for them for basic things like spark plugs, oil filters, belts and such.

Some lines like the Suzuki Carry are great, same tail light assembly for 1998-2020, same timing belt, same accessory belt, etc but that is a big thing that everyone seems to forget. Everyone "fetishizes" these cars, but most can't turn a wrench, or know how to order parts for them.

So it becomes a huge sunk cost. At the other hand, if you import them en massee, you also have a solid basis of guaranteed business. You can self guarantee a "warranty" on them for a huge premium with a "Swap out" guarantee, in case of disaster (for example, kei car is purchaed $500 at auction, shipping to USA is about $800-2000, and retail is $4500-$10,000).

That's where the marketing and service catch is at. 3 months warranty, free swap out, and then when that expires you have a customer for life, because most shops will not work on a car they can't order parts from a USA national supplier, or have access to interchange catalog.

But then it would be semi easier just to export/import whatever car was on Gran Turismo/Gran Turismo 2/Animes e.g. Initial D because those probably have minor interchange support and if there was a USA model, then parts are most likely 100% available, just that the car is in a RHD configuration vs LHD.

Some cars like a R32/R33 skyline, MK3 Supra are $$$$ priced out eternally though.
