I'm about to get a car and I have already placed a reserve on a used '08 G6 GXP sedan. I've read on consumer reports that the brakes are just horrible. On the test drive I did notice I had to press very firmly to get a solid result on the brakes. Is this normal? The car is also a certified pre-owned car so it had to pass inspection to be certified. Otherwise I like the car very much, but am just worried about the brakes. Any advice or comments?
