Dummy me, did not seem to think they looked bad at all when I changed the rear tire this past spring. Some scoring on the outer 1/4" of  the rotor doesn't look too severe.

How does it look now?

I don't konw any around here (Seattle, WA, US) that do. Maybe in your 
area. Most auto parts stores don't seem to do this any more (US).

The "new" conventional wisdom says.. don't bother. If they are scored 
severely you should be replacing them, not turning them. If they aren't 
scored that badly then they'll just eat a bit into your "cheap" (ie: 
relative to a rotor) new pads before they are properly bedded. Turning 
rotors thins the entire rotor, but it still has the same amount of heat 
and stress to deal with. If you thin it out too much then it will just 
warp.

I believe our manuals also indicate that the rotors should not be turned, 
only replaced.

That's what I would do if the scoring isn't so bad that you think you need 
a new rotor.
