@buckets0fun Outback is a lifted Legacy, not Impreza. The equivalent Subaru comparison is Impreza vs Forester, and it's a similar result, the Forester has a lot more space but the Impreza is more fun and satisfying to toss around and use for sporty driving. Chassis rigidity comparison is similar too, the CUV feels more flexy. Subaru has long offered a hatchback / short wagon version of the Impreza though, separate from the CUV Forester!
I'm aware the 3 and Y share a huge number of parts but the resulting driving experience is pretty different. After test driving a 2021 MYLR I told my wife I'd honestly rather drive our old 2013 S. If we got the Y it'd become "her car" because I wouldn't want to drive it. When we finally got to test drive a Model 3 (they had no Model 3 demos for a while) it instantly put a smile on my face. Within a few blocks I had a feeling we'd end up cancelling our other EV order (Polestar 2 Performance - a hatchback!) and buying the M3P - and that's exactly what we did.
The 3 has its flaws too of course, no car is perfect, but I find it fun to drive, whereas the Y I do not. But the Y sure has a lot more space inside. The seating is more comfortable (though not the suspension) and it's vastly better for cargo hauling. Pick your priorities.
