...the exact same thing happened to me on a rainy night in my 240z in Arizona. Slammed into the back of my car but worse than what the damage looks like to yours (although still bad) and stunned me for a second when my head hit the roof plastic over the seats. I was concussed and needed stitches but wasnt too hurt. Car was totaled and soon after moved to the z32 chassis but was always bummed I lost my S30. Still have the triple weber setup sitting around for when I break down and buy another one.
