Check what is the weight for your car
As we know, on a head-on accident, the heavier car has huge advantage. What is your car's weight?
I just ran down to my garage and checked user's manuals, here are their numbers: (look at GVWR numbers)
86 300SDL: 148 HP/4600 RPM, GVWR 4870 LBS
96 E300D: 134 HP/5000 RPM, GVWR 4555 LBS
