I'm hearing great things about the 2018 WRX. Thicker front door glass and windshield glass for reduced wind noise, improved infotainment, re-tuned suspension that is supposed to be nicer / smoother for daily driving and an updated clutch and shifter for improved feel. If I needed one car to do it all my local Subaru dealer would be my first stop and the 2018 WRX would be my first test drive.
None of the Subaru dealerships in my province allow test drives on WRXes. Sucks because they're in my price range and look like they're fun cars.
