That's been my understanding too. I do think the Korean companies have come a long way in their journeys but the cars don't have resale value and age much worse than their Japanese competitors.

The most attractive parts are the features they pack into the car for a fraction of the cost. The compromises are usually made where it's not immediately visible and for someone who changes his car in less than 5 years, I don't think it's an issue.

A lot of things are "considered" in the car fanboy circles (like german cars being considered more reliable in Europe)... and aren't true when you look at the numbers. Easy to find sources too.
