The only comment I have to this is that when buying a used KIA, or any other car for that matter, many times there is not a manual.
However, that does not excuse the new owner from knowing just what maintence to take care of/do. In todays world with the internet it not to diffcult to find the answers. Spending a fairly large amount of money and then not knowing what the maintence schudule's are just showes a lack of responsibility. And to those that do not think a KIA, even a used one, costs a fair amount of money, well then just why are they shopping in the low end isle.
