How often do you replace your rotors?

[Jake D]

I had someone meet up with me last week about purchasing my car. They were trying to talk me down in price by saying that my car is going to need brakes and rotors soon because there is a "lip" on the outside edge of the rotors.
Naturally since the brake pads don't go all the way to the edge of the rotors then there is going to be a little wear. I honestly do not think they need to be replaced and think they were just trying to beat me up in price.

I was a mechanic for almost 6 years and still continue to wrench on my own stuff. I disagree on them needing to be replaced but its neither here nor there.

Anyways, my question is, how often do you all replace your rotors. Now mind you I don't track my car or have any issues with them such as vibrations or any noise. Pads still have life on them. I have not replaced any brakes on it since I've owned it for the past 2.5 years.
