When I was P85+ shopping in 2014, the red calipers was an option you could order or decline. I believe that was still an "off menu" option for the P85Ds. Or the previous owner changed them or painted them. My P85+ didn't have them, but my P85D does. But I've never been a fan of red calipers... they're just "hey, look at me!!! I can paint calipers red!! LOOK AT MY CALIPERS!! "
