LOL! Hmm. Well, aside from Honda being Japanese and Hyundai being Korean...let's just say we're talking HUGE differences in build quality, reliability, resale value, value-per-dollar, comfort, style, and class.
I have to admit, Hyundai has improved HUGELY since the days of their first model, the Excel, a two-, four- and five-door model which sold for under $6,000 new. Many of them required new engines within the first year of being on the road, a problem that Honda never seemed to encounter. And having owned a Honda, as well as driven various Hondas and Hyundais I detailed over the years, I think Hyundai has never been able to compare with Japanese cars in terms of quality.
Honda all the way, baby!
