When can you get insurance on your car?

Hi, When you buy a car you have to do an insurance first. So that you can't face any problem in future. Nowadays, there are so many insurance companies available. But you have to choose the best one who provides you best policy. I know a company My Money Comparison, which help consumers to compare a wide range of products & services to enable them to make more informed decisions based on their personal circumstances & budget. Thanks.
