No idea if this is useful for US/CDN Honda/Acura models, but several years ago Honda UK showrooms had a small range of dealership models (cars, racers including F1, bikes various scales) probably organised by Honda Japan as I think they were made by Kyosho, Ebbro and similar. Try googling Honda/Acura US/CDN merchandise sites - you might pick up something under headings such as Collectibles or Gifts.

I've got a couple of Ebbro 1:43s "for Honda Europe" of a black NSX coupe and a white S800 convertible, both maybe 15 years old, very nicely made.
