Problem is by the time they get the truck in the garage the cost escalates to over $1000, $500 of which is what it costs just for the two rotors, then you add in all the extras like labor. With the small amount of wear permitted on the new rotors 04-08 (1.5mm) they almost always need rotors. If they're feeling especially nasty they'll turn the rotors, then tell you they can't get all the warp/groves out and then charge you to replace the rotors anyway. At one place they said they could replace the wheel bearings, which they found out they couldn't or didn't want to; the labor charge for new rotors had time to change bearings which come integral.

I hope you get the job done for what they've quoted.
