Does the tailgate open, shut and lock as it should ? Do check it thoroughly.
Or is it just dented ?
Someone hit one of my cars, not the Alphie, and their insurer tried to write mine off.
I said NO, very loudly ! It was quite old, but It had 11 months MOT.
I received a reasonable cheque, but decided a big ding in the passenger door was OK.
It still opened and closed and locked properly.
I ran it for another 4 years, Cat S. AND my insurance did not increase !
Indeed, last year I received another cheque, as, I was informed, the amount paid was unfairly low !
Amazing, but true.
So you can fight a write off decision, just make sure the vehicle will be safe however it is repaired.
