I've written a few comparisons between my 2012 C59 and my latest acquisition, a 2013 S-WORKS Venge but lets talk about the C59.
60cm traditional. I purchased it at the time I was working with a dealer and still had to wait 4 months (because I wanted MTBK and traditional geometry).
I was coming out of an original BMC Team Machine SLT01 that I coveted. http://carbonlord.com/BMCSLT01.jpg
The SLT01, very stiff and felt more like a CAAD 10 then a carbon tubed, aluminum lugged frame. I expected the carbon lugs on the C59 would give me that compliance I anticipated from carbon.
My expectations were more then met with the C59. Almost all of the stiffness of the Venge but a comfort and quality that I'd never experienced in another frame set. I am 6'3" at 190-200lbs and lay down some power, (though I am no climber at this size) I can climb exceptionally well on the C59 due to its top end performance out of the saddle. Bike weighs in as pictured at 6.7 Kilos (14.9 lbs) and there is never any brake rub or flex that I can notice.
I call it a bike that "celebrates cycling". When people ask why it costs so much I equate it to the Ferrari for an automobile enthusiast. A childhood dream of owning one realized as for many, I am thankful I am at an age that I can still appreciate it for all its worth and while I have only owned it for little over a year feel it will be a keeper, for the rest of my life while bikes like the Venge are today's trend and will be forgotten about in 3 years time in favor of the next wonder tubing/design.
Its not to say I do not like my Venge, quite the contrary I do love it, but if I had to sell one it would not be the Colnago.
I've yet to meet a person that was unsatisfied with a well fitting Colnago. I say this because the size guides between traditional and sloping geometry sometimes put people in the wrong size but what usually happens is they manage to get in the correct size, and the realization that there is not much better then the C59 holds true.
It is a legendary bicycle from a renowned manufacturer and aside of the Master X is the only true made in Italy bike left.
