I picked up a MY a couple of weeks ago. I'm good a picking quality. It's well made, as good as anything mass produced. The paint is glossy well done. Even in the door jams. The panel gaps are pretty good. Like maybe the doors are slightly different but it's like picking MM here and there. I've seen far far worse.
As to the suspension, the original tune copped a lot of criticism. Mine was built march and has the "comfort suspension". IMHO it's an ideal compromise. It's really quite compliant.. yet still pretty sporty. I drove a Ioniq 5 recently and I prefer the MY tune.
