Never had an accidental crash, but with my first car I used to crash into my mates car all the time (and vice versa)
I used to use his rear bumper instead of my breaks in the drive thru.
One day he was reversing out of a parking space and I T-boned him, later to get back at me he got out of his car when I was parked next to him and put a huge dent in my door, I just lay across the seats and kicked the dent out!
God bless £100 first cars
