Looks like it could be legit. The CarFax report checks out. It looks like it was a corporate vehicle, then was sold and became a private vehicle. There was one accident, but it wasn't sold until a year later which likely indicates that the repair went well.

Give them a call and ask some questions. Test drive it to see if it feels ok. I'd recommend an extended warranty for 4 or 5 years just to cover your butt.
