My '78 was totaled after a '60s Chevy Nova blew a stop sign and t-boned my passenger side - I was doing about 55-60, he was doing about 35. My mom was in the passenger seat.
The X spun big-time across the oncoming lane, luckilly, no contact there. Eventually came to rest on the opposite side shoulder, facing the wrong way, but with no significant injuries or fatalities.
The Nova caught the tail edge of the passenger door, and then really hit big on the rear engine compartment side. The back of the door was bent, but it still opened and closed (and latched!). But the rear structure was pretty buggared.
She had her arm rested on the passenger door armrest, with her hand inside the grab handle (her normal riding posture when I was driving) - the side impact there resulted in a few bruises on her arm, but nothing broken.
The driver of the Nova was a freshly licensed (16? 17? year old), who had saved all his money to buy the Nova, and had take up a job at a grocery store to earn enough money for gas and insurance. Not sure he got to keep the Nova after that.
I got more in insurance settlement than I paid for the car (which wasn't much), but that was a nice little plus. Used the money to buy a used Datsun 280ZX 2+2. No regrets there, but I don't regret selling it either.
To this day, I still see the X as an extraordinarily safe car, then and now. As we cut the structure apart to put in the roll cage and rotary driveline in the Lemons car, it was astonishing how much structure (and weight) is in there.
