Welcome to Team Scooby-doo. I’ve got a 2013 Legacy (it’s the sedan in the big brother/Outback line to yours) that’s closing on 110k miles that I still am a big fan of.
I've only driven it a little bit, but have really started to fall in love with it..........that being said, getting $2500 less than what I paid for my Charger in trade was jaw dropping, lol
I can’t speak to those Impreza engines specifically, but if they’re anything like the boxer that the Forester/Outback/Legacy use, keep up your oil changes, because they really like fresh synth. Also a lil’ premium tank now and then will remind you how zippy that can be.
