If the insurance dispose of it to a breaker they wont get anywhere near £2200, they'll be lucky to break a £1k
I was about to write the very same words. It will go to a salvage auction and may reach £1,000. Less maybe £150 commission.
They are doing the same as fleet disposers do when the keeper of the car has finished his lease. Far from being offered a beneficial price they prey on the emotionally attached and uninformed by asking a silly price. A few people will always pay over the odds to keep the car they've come to know. And if they don't buy it the company don't care as they expect to get much less at auction so any one they trick into paying over the odds is a bonus.
Remember a repaired Cat is worth 60% of non-Cat condition. So at best it would be worth about £3,000. Absolutely no way what they quoted. For a very low mileage car maybe, just maybe.
If you PM me I will tell you the main salvage auctioneers and you can keep watch for it to come up.
