With all due respect to the victims, parts is parts, and that's that. I once owned a 75 D350 that had a 14.5 ft flat dump bed. The bed was made from what was left of the floor of a refrigerated trailer. Seems the tractor that was pulling it was in a crash, and the driver killed. The company sent a second tractor to get the trailer. It also crashed, killing the driver and this time destroying the trailer. I ended up owning 14.5 ft of the floor of that trailer, and the Karma police never killed me.
If we all avoided any thing or place where some unfortunate soul perished, there would probably be precious little real estate left to stand on. I'm not a vulture, just not overly supersticious. And if that Belvedere was closer home, I wouldn't be afraid to bid on it for the few good bits.
