My family has both types of vans and we change them constantly over a period of 9 years. From older models to new. From what we have experienced over the years in construction is that the Hyundai is more "luxurious" than the Kia as it has power windows, more comfortable seats and a nicer stock deck. It comes with fog lamps as well. The ride is smooth and handling is very good. The only thing is that there is no double back wheel compared to the Kia. It can take some jammin and load but not much compared to the Kia. However, i prefer the H100 if i have to drive any. The Kia comes with no fog lights, the dash is pretty stock and i think the cab is more roomy. It also has manual windows . It also comes with double rear wheels at the back. It can also take more load than the Hyundai and does pretty well with maximum load. So far these vehicles can take the rough up. The only downside is that it requires more maintenence than the Hyundai. I don't like to drive it as much, maybe because they take more beating than our Hyundais. Which one do you prefer?
