Regarding rotors and "up selling" you them. Is the dealer going to remove the rotors, put them on a lathe and resurface them? They should. My opinion is the price difference to have the rotors "turned" is about 50% of the price of new rotors, so since the remove and replace labor is the same, why not just get new rotors, and have fresh brakes. Rotor thickness is one thing, but you also need to think about heat cycles. Your used rotors have been heat cycled many times, which affects longevity under use with the new pads. New rotors have not been heat cycled.
And why let a dealer do brakes in the first place? Their labor rates are more expensive than an independent BMW shop. Brake replacement is not rocket science, so why not go to an independent BMW shop, save some cost on labor to offset the price of new rotors (if they were to be added into the job at the dealer).

BMW does not resurface rotors. When they sell you them new, they're already at a tight tolerance so using a lathe on them would significantly decrease their life.
If something is wrong with your rotor, theres no fixing it, you should get it replaced.
