I can say I haven't seen the numbers of Hyundais (or any Korean vehicles for that matter) with 200K-300K miles on them like I've seen with Hondas and Toyotas. That tells me they aren't built as well. [/QUOTE]

Or that their owners aren't as rigorous with regular maintenance.

Actually, you don't even need to go back that far to see something similar. The new Accords/Odysseys are recommending using 5W-20 oil, but as recently as a few years ago, the recommended oil was 5W-30.... with the exact same engine.
