I will say its also a matter of luck. You can hit steering wheel and get internal bleeding and die.
I for instance had multiple motorcycle accidents, 1 was at 85 mph and another was 75mph when I flew into the back of a car.
Both accidents I got up and walked away from. A little scuff and body very sore from impact but very lucky in both situations esp to be alive.
I am new to this car so my opinion is very uneducated so I don't know anything about safety. I would love to see some of those numbers but honestly it wouldn't really matter to me. Obviously if its for sale it must have passed some safety regulations, and I still enjoy the car so its whatever.
It sucks you aren't s fond of your purchase, hopefully you can find a person to buy it soon, sucks playing the waiting game
