I have Arabia Insurance and their tier goes:

New Car: No fee
1 Year: 20%
2 Year: 30%
3 Year: 40%
4 Year: 50%

I think this is absolute robbery! Most cars that are only a year old still look (and smell) as if they were off the showroom floor. Who in the world came up with the idea that a one year old vehicle's parts depreciate by 20%!??? Its absurd. My 4 year old BMW still looks fairly new, but on paper the parts are only worth half price? No where else in the world would you put up with garbage like this.

I could imagine a devaluing of parts in increments beyond 5 years, but a 1 year old vehicle deserves new parts.. no questions asked.
