Seems to be increasingly common, some need replacing and some don't, many think it's a nice little earner for the garage, but a normally used auto can mean heavy brake use unless driven like a saint.

You can see the discs easily enough, is there a really pronounced edge lip say around 2mm, or can you indeed see the pitting yourself, what do your eyes tell you?

SWM's C2 VTS has covered just over 30k miles, i shall replace all discs when the pads are out, increasing wear ridge on front discs and too groovy rears for my liking....no comparison to your car but it seems to be how they go.
