Default 2005 avalanche codes

I’m thinking about buying a 2005 av from a dealer but it has codes p0060 p0137 and p0449. I’ve looked these up individually so I vaguely know what they are/entail. Does anyone have any idea what might be causing all of these at once?? Any help is appreciated

edit: has a 5.3 vortec with 200k miles

You have issues with your Evap system, as well as issues with your O2 sensor(s}. Might even be a bad ECM.

DO NOT BUY this vehicle unless it's corrected.by the dealer. If not, they can pound sand.
