"Buy back the car from the insurance company"
I wouldn't do that. There is no gain in getting involved in a Viper with major damage.
Frame damage is major damage only in the eyes of the ignorant. From what "mit" stated, it seems to be very minor.
He probably wouldn't buy some other wreck and get it repaired.
Why would he buy his own wreck and get it repaired?
Because he will stand to gain upwards of 10K (maybe even 20K). Plus he'll have a perfectly working car. This is how:
A 2001 GTS's market value is 50+K. Let's say 51K. Deductible, let's say 1K. Insurance check 50K. Nice. Now let's say "mit" decides to buyback the totalled vehicle. Let's assume buyback is 20%. That's 10K. So he get's a check for 40K. Now the damage doesn't look like it will cost more than 10K to fix, to be safe let's say 20K. So he now is up 20K.

Even if buyback is set at actual parts value, it should not exceed 20K. So he's still up 10K.

Got it!
The only thing that "mit" would have to live with is the lingering thought that the car is not "perfect" even though automotively speaking, it is.
