I have always found these American surveys a bit hard to swallow. I would have expected the German marques to be much lower, with Nissan, Mazda and Honda much higher. The two highly ranked GM marques are also a bit of a surprise.

 

Well don't forget that the "Japanese" cars are probably made in the US, the "European" cars too - or perhaps Mexico.  Some of the US cars will be made in Canada.
Then consider that a compact VW/Audi with auto transmission, DSG essentially made by US Borg Warner, but OTOH a US Ford with equivalent to DSG has a German Getreg box.

Then it gets worse, with model/platform sharing not as obvious as the old badge engineering tricks made to suit political agendas a few decades ago.

Throw in to the mix that the more (luxury) features a car has, the more that there is to go wrong (and eventually it will), and also the "Stockholm Syndrome" effect displayed by owners of utter dog marques and models, and there you have it.  You'd need your computer screen to be soft and perforated for those pages to be of real benefit.
