I have this same car. a 2015 legacy 2.5. have about 130K miles on it. When I first bought the car (brand new) i planned on keeping it until i hit 200k miles.....more recently that was revised down to 175k then down to getting rid of it next fall at about 160k miles.
other than routine maintenance (new brakes and tires and spark plugs) the only repair until recently was a new wheel bearing. currently for the past month I've been dealing with a P0420 code issue. Dealer says both of my catalytic converters are dead. $2500 for those. but i'm not sure that fixes my car as i may still have low power issues once those are put on. dead cats are a symptom of another issue and we're not sure what that is yet.
My car burns oil, this didn't start until about 75K miles. i don't have to add oil until I've driven about 3k into my new oil change, then i have to add 1 quart per 1,000 miles. so i buy oil by the case and keep oil in my trunk.
I have a feeling my oil consumption led to my eventual catalytic converter issues, but we'll see.
I like my car, the drivetrain rocks, but i don't like the oil consumption issues.
Not sure i like the car in that link.
