If we could buy Seat and/or Skoda in the states, I bet they would sell rather well. Kia and Hyundai are no longer "bargain" vehicles as they were in the past.
Skodas are quite popular in India
there aren't many cars in India compared to US or even some small European countries.
The brands that you are dismissing out of hand sell, in aggregate, several million vehicles per year worldwide. That definitely moves the needle.
