So sad to see Zeds written off by insurance companies as uneconomical to repair due to their low used prices.
I got a cousin overseas who rolled his BMW 328i THREE times in an accident.
Every panel was damaged, airbags all deployed etc.
Due to its high residual value at the time in Malaysia the insurance refused to write it off an repaired it.
I'm pretty emotionally attached to my Zed so if the numbers work I'd get mine repaired.
If there was alot of corrosion underneath or there was anything major due on the horizon like new clutch/flywheel etc, it may be an opportunity to just accept the offer and move on.
All the best with whatever path you choose
