So far in the couple years we've had the 2016 WRX, it has been an absolute delight to drive. And pretty economical if you keep your foot out of the turbo. Nothing but fluids and filter changes so far (and a battery and tires). Coming up on 52k miles and an oil and filter change, along with a tire rotation and brake pad check.
I had a 1984 (86?) Mercedes 300D and that was an impressive 5 cylinder turbo'd diesel, but it had no guts below 2000 rpm but then took off like a rocket. No issues with that one either in the couple years I had it.
My son has a 2011 F150 with the ecoBoost V6 turbo and with well over 170k miles, it runs like a champ. I was quite impressed with it when I drove it recently, and he pulls a twin axle camper all over the east coast with it.
YMMV and all that, as usual.
