I don't trust carfax. Not because I don't believe what they're saying, but there are too many variables to take into account. I have a camaro that has definitely been in a pretty bad accident, both front fenders look good from the outside, but when I pop the hood, I can tell where they drilled holes to re-shape them. Also, I have a civic that was definitely in an accident because the front suspension doesn't line up at all, you can tell from the geometry that the body of the car took a collision when trying to put the suspension together. Both cars checked out OK on carfax. that's just my 2 cents.
