You heard me right I just wish I was driving the cavalier that day

Okay this is how it happened: I do a left turn in a 50km zone and some one hits my rear right wheel. I do a 180 degree skid and now my rear axil is broken on of the wheels is broken and my trunk doesn't fit. The police didn't tell me what they thought. Now how fast do you think the other car was going considering that it hit the brake about 5m before hitting me.
