I'd be willing to trade 2 points for speeding to get my 300SD back from the grave. Being 3rd car in a 3-car chain-reaction did "total loss" damage.
Put on your "sunday best" and go to the court date. Explain to the nice judge that you didn't realize you were going that fast, light traffic, nice day, etc.
Hope they don't consider the 60 day suspension, which I'd guess they won't given your clean record.
Best of luck.
