I am looking buying a '12 128i from a friend of mine. It is a base coupe with few options and has 110k miles and he is asking $5500 for it. I just took it for a test drive and a couple of things:

While driving on the interstate I very gently push the brake pedal and the streering wheel oscillates back and forth. When I press harder it goes away. I realize that the rotors might need to turned or replaced. Anything else I should be concerned with regarding the brakes?

The A/C system seems to not operate properly in the Auto setting. It runs for several minutes and then switches to the defrost vents, when I manually select the main vents it blows out of the main vents until I select auto and the cycle repeats. Is this a common problem?

Any other items I should look at or be aware of?

Thanks in advance,

Bob
