In the old days, almost all cars and trucks were built like tanks. The frame, the body, the bumpers, everything. Even as late as 1979, Dodge put such a sturdy bumper on the front of its pickups that when my No. 3 son ran my 79 Dodge pickup off a dirt road at high speed about 6 years ago because he lost control, and took out 11 wooden fence posts that were 4-5" in diameter, snapping them like twigs, along with the strands of barbed wire on the posts, he hardly dented the bumper. A body shop popped the dent out for very little cost. It also cost very little to replace the left front headlight and the small dent in the part of the body panel that the headlight was set in. Those three things were the only damage to the truck. Try taking out those fence posts with any modern car or truck and see what happens.
