I would have to personally know the seller to even think of proceeding on this one. The scams can be pretty sophisticated. At the very least check the VIN number for being stolen. I still wouldn't touch it.
In addition, this is a 2011 bike, for which the current spares situation, even down to OEM tires, is a supply chain nightmare. OK, all bikes new or old can need parts, but getting Can Am to provide new parts for a current production series bike has to be more likely than getting parts for an 11 year old machine that you don't know has truly been treated. Even with 12000 miles and a service history, something 11 years old will be more prone to aging of wiring and plumbing, especially as those things ran pretty hot. Unless you do all the work yourself and are willing to source used spares off E-Bay or similar to guarantee supply, I would avoid it.
That's just me.
