I think the OP's list is one about favorite brands, not really best auto makers, because that is kind of impossible to decide.
In my experience some of the "top" brands in the recent past like Toyota and Honda are getting slightly worse in quality while other brands like GM and Chrysler are "trying" to get better. This isn't to say Honda and Toyota are junk, just that like all things across the board they have cheapened a bit.
I would say Honda is pretty close to the top right now. Toyota would be second. I have seen some pretty significant problems with Toyotas that Toyota motor co. denied existed or refused to fix. I know a few Toyota owners who bought one thinking they were bullet-proof and won't be buying one again. Mainly because of severe oil consumption problems on almost brand new vehicles.
With that said I don't think any one brand can be the best. Every single one of them produces good and bad vehicles, it is all about what you look for in a vehicle and your perspective. Sometimes the good versus the bad can even get down to one model being reliable with one power train, and an absolute nightmare with another power train. I know a guy who only buys Mercedes-Benz because every other brand is "cheaply made" in his opinion. He also thinks the high maintenance costs are acceptable where someone else may think replacing tires every 20k miles is insane. It's all perspective, and why there are so many different brands out there.
