What did you get pushed into? I'd say the fact you obviously were pushed into something else is what caused the severity of the damage. I got hit by a '77 F100 doing approx 45-50 mph at impact with my '81 Jimmy and it didn't look half as bad as your burb does. I didn't have anyone in front of me though. I heard the tires lock up behind me, saw there was no cross traffic so I took my foot off the brake just before I got hit.
You're gonna be plenty sore tomorrow!
