This type
of insurance is a step up from third party insurance,
in the sense that it also includes cover for fire damage
and theft. If you think you need more car insurance
but still don't want to pay for a fully comprehensive
package, this might be the policy for that's right for
you.
Because it does provide a little
more coverage than third party insurance, it costs
slightly more, but it tends to cost much less than
comprehensive, so the benefits outweigh the drawbacks.
In the end, it's your choice.
