John,

Take it to a local body shop, I did before I purchased my X5 just to double check. The first thing they'll look for is bolt replacement under the hood, or alignment of the bolts to the main frame. If those are original and have never been touched, the vehicle was never in a serious accident. That doesn't mean that something minor didn't occur, normally minor accidents aren't reported on nice cars because it would bring the value way down, therefore not on a carfax report. Also, check the alignment of all your doors by standing in front of the car in the sunlight and looking at the tops of the door frames (look to see if they all look even etc..). Again, check the the bolts in under the hood, or have a pro do it, if those have been touched, your car was in a serious wreck and that would constitute a refund even if the guy stated he had no prior knowledge. Sorry to ramble, just trying to help. GL.
