I think the broader point to note here is that it's relatively easy to build simple machines. It's hard to build reliable complex machines.

I would certainly trust a low end Ford Focus, more so than even a low end VW Golf / Skoda Scala.

As soon as you move into premium models both the American and European manufacturer start to show their weaknesses compared to the Lexus/Acura/Infiniti/etc brands from Japan.

Tesla is an American brand. I would argue Ford/Lincoln is the best Detroit motor company. GM makes meh cars. Chrysler is no longer American.
