Third party insurance car insurance only covers the costs of the other persons damages - you have to fund your own car's damage yourself. To cover your own damage you can buy comprehensive cover but often this is expensive and may not cover everything that you want it to.
There is now a new cost effective option - PeerCover. With PeerCover you and your network can cover the cost of damage to your own vehicles. You do not have to change insurance - you can still use your current third party insurer to cover the cost of other people's damages.
PeerCover is flexible - choose the level of cover and who you want in your PeerGroup. You can even choose to have no-one else in your PeerGroup and use PeerCover as a way to save in order to fund the cost of your own damages. With PeerCover you and your PeerGroup make a deposit through PeerCover (to fund future claim costs) but unlike insurance if no-one in your PeerGroup claims you get 100% of your deposit back.
PeerCover only charges a small fee ($100 per claim) to provide the service - so PeerCover may be what you have been looking for to supplement your current third party only car insurance.
