Looking to trade my 2012 Large Aluminum Mach 5.7 frame for a Large Mach 4 frame, preferably the same year. Will also consider trading the entire bike in stock form. It has the XT build from Pivot on it. The bike has very little hours on it and only a few minor scratches. I've decided to stick with a more XC oriented bike these days, and love the Mach 4.
