The Texas plumber who is suing AutoNation for $1 million says his family received death threats after a pickup truck he traded in with the car dealer ultimately ended up in the hands of ISIS fighters in Syria. Mark Oberholtzer says he traded in his black, Ford F-250 pickup truck at AutoNation Ford Gulf Freeway in Houston and was told the dealership would remove the decals of his company logo from the truck on their own to avoid scratching the truck's paint.
