I have no clue how Subaru
I have no clue how Subaru ranks so high. I own a 2015 WRX and while it has held up mechanically, the quality of materials, paint, and the piss-poor leather quality is a joke. So is the crappy head unit, but at least I can upgrade that.
As for Mazda, I 100% believe it. I also have a 2010 CX-9 GT that I think is a pretty amazing vehicle. We've owned it for 4 or 5 years and I've only done the basics (brakes, oil, tires etc) for the last 50k miles. The interior has held up very well for 115k miles too.
