I think you got a great deal. That rear end is tough and could have taken a much harder impact and shrugged it off. Remember the CJ's and their two piece AMC 20 rear axle shafts? Well, before I could buy the one piece alloy conversion set, my driver's axle hub broke free of the shaft and I have left in the middle of a dangerous country intersection. When it broke, I spun out like a top. Considering the safety involved in the issue, I just gassed it and drug the Jeep to the side of the road on the brake backing plate leaving a long gash in the highway. Trailered it home, installed the new upgraded shafts, bolted the tire back on, and drove it to school. No less for the experience. Of course, the dealership was very much in the wrong and I would have gotten a lawyer immediately for punitive damages (these things never make it to court). My point is, that the Raptor (and F150) is really, really tough and can withstand much more abuse than this accident could dish out. I also doubt the Carfax issue. Have you checked to see if it's on your report? I doubt it is.
