A couple of years ago a guy in a Toyota rear-ended my 79 300sd...the front of his car was BADLY crumpled, his airbag went off....It looked like he hit a wall!
I barely felt the impact. It felt like I hit a pothole or speed bump or something. The only damage to my car was bent bumper mounts\shocks. I went to the Pull-a-Part salvage yard and got mounts for $13, and pocketed the rest of the $$.
