I concur my good man!

Being one who paid $500 back in 2014 for a 2006 Pilot 2.1 - Bike Archive - Trek Bicycle with the exact same Ultegra 6600 FD and RD combined with 105 brifters, I have to say that even after I paid $50 to have it shipped from Dallas I still feel I got a solid deal. Of course mine did not have the cosmetic damage like the one your considering.

For me one of the most important things to look at (and I did request from the seller additional pics of all the joint in the frame) is make sure there are no serious dent or especially cracks that could break down the road. The fact is the premium your paying is unquestionably for the brand name
