Let's get beyond the specific question. Those Colts are pretty, and the quality is good. But that gun is (IMHO) overpriced. Further, it is not untouched because it has drag marks.
The question for Rambutan is whether he wants a pretty gun to look at or a gun to shoot.
If he wants to use the gun, my advice is to buy a Ruger which will keep going about forever and not have any collector value to lose every time it is fired.
If he wants a nice gun for a collection and doesn't mind paying for the Colt name and appearance (and paying $800 for a $600 gun), then he should go with the Colt.
