Why is this downvoted? It's absolutely true, and disproves the parent's point. Japanese cars are probably the most popular here (I'll take his word for it, it certainly looks true just looking at the cars I see on the road, and if it isn't true, it's close), and they aren't expensive to fix at all. Parts and service aren't a problem at all.
The parent obviously doesn't remember the terrible reputation British cars got in the 70s.
It doesn't disprove anything. Some Japanese manufacturers have a good supply chain and service to the US, it doesn't preclude that plenty of other brands don't.
The supply chain wasn't the problem with British cars, the problem was the engineering was terrible. They were renowned for being extremely unreliable.
