I have a two year old Ford Fiesta. My insurance agent is recommanding to take Zero Depriciation Addon. Just wanted to know your views on it. Whether it's worth buying.

Share your views!

Thanks,

If you meet an accident 3-4 years in future then Zero Dep will make really big difference because you car's value will just be 70% of the new car's price.
