RS7 brakes
 

My wife has a 2014 RS7 that has just turned 30,000 miles. She does not hammer it ever but the front rotors are badly scored and the dealership (Scottsdale Audi who are great and I trust them completely) tell me the rotors can't be machined and need to be replaced along with the pads at a cost of about $3,000. I have a few high-performance cars which I do drive a lot harder than my wife but have never had to replace rotors. Does anyone have any experience with this?
