Not really, sit in any recent Korean car and you'll find out that it is screwed together just as good as Japanese or German cars. Super premium hatches will have better materials(a45 for e.g.). But even recent BMW's suck interior wise. Audi is the one that seems to do well even on the lower end.
Unless you start taking off panels and actually working on it, it's hard to tell just by looking. With cheap panels the clips etc break off really easy. They also scuff easier.
