Come to the conclusion that my time has come with my S401. It'll be leaving my hands in the coming months, as I simply cannot afford to own and run it with my other half wanting to do lots of road trips, as she's seen a lot of the world, but barely any of NZ (I'm the opposite lol).
I've already found its new owner, which is a good friend of mine. He'll be continuing what I set out to do with it, which is tastefully mod it, namely on the suspension side - he's not too keen to change the engine up.
What will I be replacing it with? Well... a motorbike for starters - a 2019 Royal Enfield Continental GT, and as for the car, a 2010-2013 Mazda 6 GSX wagon (the update one, as they get a lot of extras standard vs the release model). Having one of those will enable road trips for the both of us, and also her to drive it, as she's not a confident manual driver, and the Mazda will be auto.
I do plan to own another Subaru in my future, but the time is not now. Probably when my grey hairs start to develop lol.
