I bought a new Mazda 3 after this and I think I might have opened the door and walked out of the car if the accident had happened with the new car. The roof shouldn't have buckled, the floorboards and dash shouldn't have moved towards me, and the brake pedal shouldn't have broken my leg.
On the other hand, I did get hit at 60mph mostly on the driver side in a rusty old car by a car that outweighed mine by 300lbs and I lived. The other car (91 Dynasty) faired a lot better, probably because the impact was more centered and straight on (it's in the background).
The Grand Am still looked like a car from the passenger side:

For the first few weeks after this I wished I had been driving a 3/4 ton truck, but the bitterness subsided and I suppose it's better that we both lived.
