I just found a trek 560 today in okay shape, as some of you already know from the COTD thread. I have a few questions as to what will or won't destroy the perceived "value" of this fine machine. I am thinking of going for a powder coat repaint if I can find a perfect match for the slate gray 83 color. I've heard time and time again the old adage "it's only original once". Would I be making a mistake to repaint it? I can clean and touch up the bad spots, or would this be considered the same thing? I so want to have some decals made and make it look as close as possible to showroom fresh. But, I can live with it not being perfect, too. I like the vintage look on certain bikes.
Next comes components. I have a Cyclone MII derailler set I could install for a little bling. Well actually it's a 78 Cyclone front, and an MII RD that is very close to NOS condition. The bike has what I believe is the original Suntour BL (blue line?) Would the Cyclone be an upgrade or step down? I know the Cyclone is decent rank in the lineup depending on year, and the very clean components would look very nice with a new paint job. They're not permanent, and I have the ability to hang onto components for years for originality purposes. Is one better than the other, are they equal?
Opinions, truths, suggestions? Anything is open to discussion, except selling the bike
