Yes, I hear that, and more frequently than I would prefer. But my own Kia dealership is also my Hyundai dealership, and their reputation is about the best of any in town (and deservedly so). But I also have two other dealers within 50 miles. One is also a combined Hyundai/Kia dealership with a lousy reputation (also well earned), and the other have separate Hyundai and Kia franchises, with the Kia people having a bit better rep than the Hyundai people.
I've said it before. You would think by now that car manufacturers would have learned that service reputation is EVERYTHING these days. But apparently not.
