Let them total it, buy it back from the junkyard that they sell it to. You can get it for SOOOO cheap... my brother did this with his 77 corvette, it had frame damage and the whole deal, he bought it back for 500 dollars, and insurance paid him 13K for the loss of the car.... see where I am going on this... get the car, and what the car is worth... then go for doctor bills and compensation!
I am sorry about all this man... I truly dont believe that people that old should be on the roadways without being carefully looked over first (I think that they need to pass lots of tests every so often in order to make sure that they are road worthy). I hate to see MKIII's go down like that.... why can't it get a more respectful death? Why can't the car just not die... that would work too.... it blows man, it really just blows.
