If your car gets hit to the point where you have to replace body panels it's not as mechanically sound any more as you might think. Only weird, edge case accidents can result in a body panel being destroyed to the point of replacement where the actual structure of the car hasn't been bent or warped in ways that will permanently alter the handling and behavior of the car.
As for being green; when you write off a car it's not like it just gets buried in the ground whole. It gets parted out and the parts all get sold. It's actually quite green. :P
Your insurance will give you replacement value for the car that was destroyed. No that's not original MSRP but it's what the destroyed car is worth. If you're really intent on repairing it, you usually use that money to buy the written off car from whoever the insurance company ends up selling it to (usually whatever mechanic or storage place the totaled vehicle is physically located) and then pay to have it repaired. If the total of that procedure is higher than what the insurance company gave you, then it's a bad idea to do that. :)
