My mom got hit head on by a 67 caddy 4door, she was driving a 69 ford mustang. The angle of impact saved her life. The caddy was doing over 70 according to witnesses when it crossed the highway divide and hit my mom doing 55 head on. The angle was such that the caddy peeled her front driver side fender off, and folded the Mustang in half, popping the rear axle off. Mom got a broken arm and some whiplash. The caddy had 3ft of the engine compartment inside the cab. When the pried the drunks out, beer cans hit the highway and rooled around. The cop on scene said if it had hit just a few inches more towards the center of her car she would be dead.
Point is it's all in the angles, where the frames are mounted to body etc. I would have bet on the caddy that day, but was gratefull to see my Mom walk in the front door at two a.m.!
