Keep your eyes open, you may see the same car again.
For the form that the link was posted earlier, you are required to get two quotes. From seperate shops, your claim is treated exactly the same as that of any other vehicle on the road.
Get down what happenned on paper. Doesn't have to be in order to start with. You'll work through that list & put them into order. Ambulance called, see if you are able to get the names of the person who called it. Serves two reasons, time & location of the incident & a possible witness..
As others have said Get Well Soon.
