So I am thinking about getting an Avalanche XTE. A guy locally has a new never used one, for what Ifeel is a pretty good deal at $275.00. I've never messed with the electrics much. Is there anything should upgrade right away on this model if I decide to go with it?

It looks pretty damn fun in the video. But, with all things I am sure this has a weakness. So I am looking around for suggestions.
