Hyundai/Kia took marketshare away from the Japanese by pricing their cars below those brands while trying to make better and better cars. That should be (I think is) the pricing strategy of GM with Cadillac. The CTS is cheaper than the German three, Lexus and Infinity if you factor in rebates and compare similarly equipped mid-sized sedans.
Be honest, which of you would actually buy the ATS instead of any of these at the same price: 3 Series, A4, C Class, G37, GS...IS?
