How do I get car insurance?

This can be quite tricky. First off, you can only buy insurance at a practical price if you stick to Europe and a bit beyond (e.g. Turkey). Secondly, don't mention 'rally' to any insurance company or they will think it is a race. Just tell them you are going exploring.

One useful trick is to cancel your UK insurance on the date you leave Europe, as outside Europe you buy the insurance at the border of the country you are driving into. They will only cover you third party. It is possible to get full cover but don't expect to get any money in the event of an accident!
