Is there a reason I shouldn't buy a Kia instead of a Honda?

i would stick with civic, it is not so bad with 100k for honda just make sure change the timing belt and water pump. The only consideration about kia is the resale value and well, the quality still far less than honda. Another thing is the mileage 4 cyl civic VS 6cyl kia. You can still save some money out of it too on the long term. Good luck
