I also own a GR Corolla. it's a fantastic car.

I think its a pretty amazing engineering feat to combine Toyota reliability + 1.6L of engine + the weight of a hatchback + 300hp. Sure, not the best exhaust note, but probably such a fun little monster to drive.

I'd say the reliability statement is still a bit early (GRC has been out four years, GR Yaris with same engine has been out about 5-6). But so far it does seem fairly reliable at least up until someone decides to push the power limits for various components.

It's insanely fun. I previously had a BRZ which was also a lot of fun. This is a whole new beast. Especially in not ideal conditions (wet road in the fog on a mountain and presumably in snow or dirt).
