This is a tough one . Where are the chips? Are they really noticeable? Will it cause long term problems with the carbon fiber? Will Trek replace the frame down the road (if it fails) if they give you a discount now?

I got $600 off my frame due to a teeny scratch on the head tube, a spot that's covered by my cables. My bike's Alu, and it was NOS, so I was already getting a crazy deal on it. If it were carbon, and it was this year's model, I'd want much more than $600 off, and a warranty.
