I recommend doing some more research. China is the largest car market in the world.
Regardless, manufacturers offer a significantly wider variety of vehicles in their home markets than they do in the US. There is definitely more variation.
The only real thing the US car market has going for it compared to other markets is more horsepower and larger SUVs
The large SUVs are actually a detriment to mobility over seas.
Once again, highly highly encourage waiting to see where you’re gonna be and just getting a car there.
