Do some research on how many Silver in your year were made, with your options.... Play up the "Rarity" of the car. That is IF you want to save this one.
Amazing what six weeks in good shop and $14,000 in insurance money can do for a Marauder.
Don't settle until it's done. The other persons insurnace should pay to have it fixed. Go slow and remember, the first prioriity is everyone involved is healthy. Then deal with the car.
